When exposed to the same amount of heat for the same amount of time, a 3 g sample of copper will experience a greater temperature change then a 12 g sample of copper due to its smaller _

MASS

Explanation:

Formula for heat energy will be;

Q = mcΔt

Where;

m is mass

c is specific heat capacity

ΔT is change in temperature

Now, since both substances are copper, it means they will have the same specific heat capacities.

Thus, from the formula given earlier, it is seen that the mass is inversely proportional to the temperature change.

This means that the smaller the mass, the greater the temperature change.

Thus, the 3 g sample of copper will experience a greater temperature die to its smaller mass

the answer for sodium is 0.186

the answer for rubidium is 0.251
