Explanation:

Granite is an igneous rock that forms when magma cools slowly underground. When granite is exposed to heat and pressure it changes into a metamorphic rock called gneiss

Answer:

THERMAL IMAGING

We can sense some infrared energy as heat. Some objects are so hot they also emit visible light—such as a fire does. Other objects, such as humans, are not as hot and only emit only infrared waves.

Answer:

0.93 grams per milliliter

Explanation:

Density is the division of mass by volume. It is how "hefty" an object is; for example, wood isn't very "hefty" but metal is. The density is measured in mass over volume, so it is 9.3/10. After applying units, it is 0.93 grams per milliliter.

Answer:

6%

Explanation:

Actual length of the wood is 2.5 m

Observed length of the wood is 2.35 m

We need to find the percent error of your measurements. The formula of the percentage error is given by :

[tex]\%=\dfrac{|\text{observed-actual}|}{\text{actual}}\times 100\\\\\%=\dfrac{2.5-2.35}{2.5}\times 100\\\\\%=6\%[/tex]

Hence, the percentage error is 6%.

Answer:

Option B:

Conduction

Explanation:

Conduction is the transfer of heat from one molecule to another between two solids that are in direct contact with each other. For the conduction of heat to occur, the medium involved must be solid. This is because the molecules of solids are closely packed together and they cannot freely move about. The heat flowing through them can easily be passed on from one molecule to the other until it reaches all the parts of the object. This is exactly what will happen to the iron bar. Thermal energy from one end of the bar will get transferred between the molecules of the iron bar until it reaches the other end.

Convection on the other hand involves the transfer of heat through a liquid medium.

Radiation involves teh transfer of heat in a vacuum.

Answer:

b) conduction

Explanation:

Explanation:

Compound: a substance that is made up of more than 1 type of atom bonded together Example: H2O

Mixture: combination of two or more elements or compounds not chemicaly bonded together. example: Sugar and salt in one container

elements pure substance of an atom. Example: hydrogen

Answer:

Only Hydrogen and Group 1 elements have 1 valence electron

Explanation:

the valence number of electrons is the group number in the periodic table. So, the group 1 atoms( along with hydrogen) have 1 outer-shell electrons [valence electrons]

Answer:

Temperature affects the kinetic energy in a gas the most, followed by a comparable liquid, and then a comparable solid. The higher the temperature, the higher the average kinetic energy, but the magnitude of this difference depends on the amount of motion intrinsically present within these phases

Answer:

How do solve the uncertainly of a number??

Explanation:

If you're adding or subtracting quantities with uncertainties. You add the absolute uncertainties. If you're multiplying or dividing, you add the relative uncertainties. If you're multiplying you multiply absolute uncertainties by the same factor, or do nothing to relative uncertainties.

Answer:

If you are taking a with power of a number with an certaintly ,you multiply the realtive uncertainty by number in the power .

Changing the particles changes the atoms by converting it to a new substance through bond change.

During a chemical reaction changes occurs in the atoms of an element due to the formation or breaking of bonds.

There is either loss or gain or sharing of atoms between two elements reacting together.

Bonds between atoms break and new ones form and energy is either given out or taken in.

This type of reaction leads to the formation of new substances made up of a new combination of atoms and a different configuration of electrons.

Therefore, because various changes occurs during a chemical reaction, changing the particles changes the atoms by converting it to a new substance through bond change.

Answer:

Randy went into the classroom without the teacher being present. He opened  containers of chemicals without the teacher's consent. Randy is making contact with the chemicals on his skin.

I hope this helps! I haven't done lab science in a while so I'm trying to remember the safety precautions.

Randy went into the classroom without the teacher being present and opened  containers of chemical, making contact with chemicals on skin leads to skin reaction.

So Randy should follow the lab safety rules while entering into lab.

After entering lab wear apron and gloves along with safety goggles if working with any hazardous or infectious substance.

Fully aware about the hazards of the materials, properly trained to handle lab equipment, chemicals should be adequately labelled.

Taste or smell chemicals are prohibited, never pour already stored chemicals, chemical hygiene plan should be developed for specific hazards.

Avoid to adopt un-tested and unauthorized experimentation, Clean up all chemical spill, Laboratory induction should be carried out .

Avoid storage of any edible items in the refrigerator along with lab chemicals and specimens, clean the work station after completing experiment and sterilization should be done before starting experiment.

An independent variable is the cause. Its value is independent of other variables in your study. A dependent variable is the effect. Its value depends on changes in the independent variable

Variables are the factors or the numbers used as a quantity. The dependent variables are conditional, and the independent variable is the cause that affects the result.

The independent variable of an experiment is the data that is the cause of the experimental design. Its value and result do not depend on other factors and conditions. These values are manipulative and are set by the researcher.

The dependent variables, on the other hand, vary based on the other factors and variables and are the effect that is based on the response and the outcome of the other variables. It is the tested or the measured value.

Therefore, the independent and dependent variables differ based on cause and effect.
