Suppose you do a calorimetry experiment to measure the specific heat of a penny. You take a number of pennies, measure their mass, heat them to a known temperature, and then drop them into a container of water at a known temperature. You then deduce the specific heat of a penny by measuring the temperature change of the water. Unfortunately, you didnāt realize that you dropped one penny on the floor while transferring them to the water. This will:
A. Cause you to underestimate the specific heat.
B. Cause you to overestimate the specific heat.
C. Not affect your calculation of specific heat.
