Question 30
H

A student finds the specific latent heat of fusion of ice by melting ice with an electric heater and collecting the water. Some extra ice melts because of energy from the warm room. How does this affect the value obtained?

[1]
A

The value is too large, because the energy measured is larger than it should be

B

The value is too large, because the mass measured is smaller than it should be

C

The value is too small, because the energy measured is smaller than it should be

D

The value is too small, because the mass measured is larger than it should be
