Suppose a 10 mL beaker and a 100 mL beaker are both filled with water, and that the water in both beakers is the same temperature. Which statement below about the water in the two beakers is true?

a. the two beakers of water contain equal amounts of heat

b. the larger beaker of water contains more heat than the smaller beaker

c. the smaller beaker of water contains more heat than the larger beaker

d. it is not possible to determine which beaker of water contains the most heat because heat cannot be measured

Reagan Coleman · Answer 1

The larger beaker of water contains more heat than the smaller beaker.

Dharma · Answer 2

The correct choice is

b. the larger beaker of water contains more heat than the smaller beaker

Reason:

Heat is given as

Q = m c T

where Q = heat contained

m = mass of water

c = specific heat of water

T = change in temperature.

since the specific heat and temperature is same for both the beakers, we need to look at which beaker contains more amount of water. the larger beaker has more mass of water, hence heat contained in the larger beaker is greater.
