Heat in a substance is an example of energy. a. phase b. kinetic c. potential d. evaporative

Option (B) is the correct answer.

Explanation:

When there will be flow of energy from one substance to another then it is defined as the heat.

Since, heat is responsible for the movement of particles of a substance. This means that more if the heat more will be the kinetic energy as kinetic energy is the energy obtained by particles of a substance due to their motion.

Also, kinetic energy is directly proportional to temperature.

                     K.E =

So, more is the temperature of an object more will be heat transferred by it. Therefore, more will be its kinetic energy.

Thus, we can conclude that heat in a substance is an example of kinetic energy.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
