Question

Which statements are true about a block of ice at -10° c as you continue to apply heat?

a) its temperature will not rise above -10° c until it melts
b) its temperature will remain at 0° c until all the ice melts.
c) its temperature will rise continuously until it completely melts
d) its temperature will rise until reaching 0° c

Answer 1

The temperature of a block of ice at -10°C will remain at 0°C until all the ice melts.

Step-by-step explanation:

The correct statement about a block of ice at -10°C as you continue to apply heat is that its temperature will remain at 0°C until all the ice melts.

During the process of melting, the temperature of the ice does not rise. Instead, all the energy being added to the ice goes into the melting process and not into an increase in temperature. Once all the ice has melted, the temperature of the water will rise.

This is because the heat being added to the system is being used to overcome the attractive forces holding the solid ice together, rather than increasing the temperature.
