Which one has more Thermal Energy? A cup of boiling water or a bathtub of warm water? Explain! Please answer if you can, thank you!! P.S this is science but i just put it as chemistry?
Answer:
See explanation
Explanation:
The thermal energy of a substance is affected both by its mass and by its temperature. Thermal energy is defined as the total kinetic energy of all particles in an object.
Even though the cup of water has a higher temperature, the bathtub has more thermal energy because it contains much more mass of water compared to the cup. It will release more thermal energy to the surroundings compared to the cup of boiling water.
The bathtub of warm water has a higher total thermal energy due to its bigger volume, but the cup of boiling water has a higher average kinetic energy per particle.
The thermal energy of a cup of boiling water is greater than that of a warm bathtub. The sum of all the kinetic energies of the particles in a substance is its thermal energy. The temperature of boiling water is higher than that of warm bathwater. The average kinetic energy of the particles is measured by temperature. The average kinetic energy of the particles in a cup of boiling water would be higher than that of the warm water in a bathtub, which is normally between 38 and 45 degrees Celsius (100 and 113 degrees Fahrenheit), because water has a boiling temperature of 100 degrees Celsius (212 degrees Fahrenheit).

You’ve been waiting for the bus and your hands become cold. When you get onto the bus and sit down, you put your hands under your legs to warm up. After a while your hands feel warmer but your legs feel colder. Explain this with regards to what you know about thermal energy transfer.
Explanation:
The First Law of Thermodynamics states that energy cannot be created or destroyed in an isolated system. In other words, energy can be converted from one form into another, but it cannot be created nor destroyed.
Conduction is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, which can take place in solids, liquids, and gases.
When you put your cold hands under your legs to warm your hands up, the heat energy from your legs is being transferred to your hands through conduction. However, since energy cannot be created, there is no extra heat energy that can instantaneously replace the heat created by your legs.
Every metabolic process involves energy transfer. Since as the total energy is conserved and thus no loss or gain of energy will be there in a system and to maintain this equilibrium energy transfer from lower energy spot to higher energy spot.
What is thermal energy?Thermal energy is the energy in the form of heat and which can transfer from one part to the other as any other energy form.
As energy is conserved in a system there will be no net gain or loss of energy overall. Thus energy lost from one part travels to the other parts. Any energy forms transfer from a low intense area to high intense area.
When our hand cools down we may warm them up by rubbing on legs. Where heat energy is transferred from our legs to hands to warm it up. Thus here temperature is given to a colder part from a hot part.
This is an example of heat transfer hence, our legs cools down because some of its temperature is lost to hands still the overall temperature of the body remains balanced.

6. 1.98 × 10^−31 Hz
7. 8.97 × 10^10 Hz
8. 1×10^6 Hz
9. 6.65 × 10^−18 Hz
The frequency(f) of this photon : 1 x 10¹⁵ Hz
Further explanationRadiation energy is absorbed by photons
The energy in one photon can be formulated as
[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light
= 3.10⁸
λ = wavelength
A photon has a wavelength of 299 nm.
λ = 299 nm = 299 x 10⁻⁹ m = 2.99 x 10⁻⁷ m
The frequency :

A gas is allowed to expand from a volume of 400 ml to 2000 ml at a constant temperature. If the the initial pressure is 3 atm, calculate the final pressure exerted by the gas
Answer:
[tex] P_{2}) = 0.6 \; atm [/tex]
Explanation:
Given the following data;
Initial volume = 400 mL
Final volume = 2000 mL
Initial pressure = 3 atm
To find the final pressure P2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 3 * 400 = P_{2}* 2000[/tex]
[tex] 1200 = 2000P_{2}[/tex]
[tex] P_{2}) = \frac {1200}{2000}[/tex]
[tex] P_{2}) = 0.6 \; atm [/tex]

All of the alkaline earth metals are similar in that – they are all artificially made elements they all have similar atomic weights. they all have the same ionic charge. they all show variable valences.
Answer:
they all have the same ionic charge.
Explanation:
Alkaline earth metals are group 2 metals on the periodic table. They are divalent elements because they have two valence electrons and ionize by donating these two valence electrons. Elements in this group have the same numbers of electrons in their outermost shell of their atoms. i.e. they all have the same number of valence electrons and ionic charge.
A sample of gas occupies a volume of 598.9 mL and has a pressure of 675.6 torr. What will the pressure of the sample of gas be if the volume is decreased to 235 mL? Be sure to include units with your answer.
Answer:
1721.77 torrExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question we have
[tex]P_2 = \frac{598.9 \times 675.6}{235} = \frac{404616.84}{235} \\ = 1721.773787...[/tex]

the density of seawater is ____ fresh water?
Answer:
Since salt ions are heavier than water molecules, seawater is denser than freshwater. The density of seawater ranges from 1020 to 1030 kg/m 3 while the density of freshwater is about 1000 kg/m 3. Variations in salinity also cause the freezing point of seawater to be somewhat lower than that of freshwater.
