Question

Ice contained in a beaker starts melting when

• A. the specific heat of the system is zero
• B. internal energy of the system remains constant
• C. temperature remains constant
• D. entropy remains constant

Answer 1

Answer: (C)

temperature remains constant

When ice is contained in a beaker.
The temperature of the ice keeps falling till $0^{\circ }C$ after which the heat loss is responsible for conversion to water, the temperature will not change.
Hence the temperature remains constant.
Option C is correct.
