Answer:

Charles' Law

Explanation:

If a sealed container of gas were placed in a fire, the temperature and pressure of the gas would increase until the container broke or exploded. ... to volume when temperature is constant.

In the case when the bottle should be thrown into the fire so here Charles' Law should be applied.

Charles's law is a statement where the volume should be occupied by a fixed amount of gas that should be directly proportional to its absolute temperature in the case when the pressure remains constant.

Since in the case when the sealed container of gas should be placed in the fire so here the temperature and the pressure should be increased till the break of the container.

Gallium has three valence electrons.

Elements in the periodic table are classified into groups and periods. Elements in a given group have the same number of valence electrons on their outermost shell while the elements in a period have the same number of shells.

All the elements in group 13 have three electrons in their outermost shell. Gallium is an element of group 13. This means that gallium also has three electrons in its outermost shell(valence electrons).

Gallium has 3 valence electrons (1 electron in the 4p orbital and 2 electrons in the 4s orbital) because the valence electrons are those located in the outermost energy level of an atom.

Gallium has an atomic number of 31, which means it has 31 electrons in total. The electron configuration of gallium can be represented as [Ar] 3d¹⁰ 4s² 4p¹.

Within the n=4 shell, gallium has electrons in the 4s and 4p orbitals. The 4s orbital can hold a maximum of 2 electrons, while the 4p orbital can hold a maximum of 6 electrons. In the case of gallium, there is 1 electron in the 4p orbital.

c = 0.38 J/(g-°C)

Explanation:

Given that,

Mass of copper, m = 5 g

Initial temperature, [tex]T_i=35^{\circ} C[/tex]

Final temperature, [tex]T_f=22.6^{\circ} C[/tex]

When copper cools, it looses 23.6 J of heat. We need to find the specific heat of copper. The heat lost is given by :

[tex]Q=mc\Delta T[/tex]

c is specific heat

[tex]c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{23.6}{5\times (22.6-35)}\\\\c=0.38\ J/g-^{\circ} C[/tex]

Hence, the correct option is d.

Answer:

His measurements will be more precise if he uses a graduated cylinder that measures to the nearest tenth of a mL.

Explanation:

His measurements will be more accurate if he uses a graduated cylinder that measures to the nearest tenth of a mL. The correct option is B.

The closeness of a measurement to the real or recognised value is referred to as accuracy.

The learner can achieve more exact measurements and eliminate the possibility of rounding mistakes by using a graduated cylinder that measures to the closest tenth of a millilitre.

This enhanced precision will help to improve measurement accuracy. Taking measurements from more flowers (options A and D) will expand the sample size but will not enhance accuracy unless the measuring device is updated.

Option C recommends improving precision but does not address accuracy.

Thus, the correct option is B.
