Question

A liquid is heated in a well-insulated container. The power input to the liquid and its specific heat capacity are known. Which of the following quantities must be known in order to calculate the rate at which the temperature increases? A. The time for which the liquid is heated B. The initial temperature of the liquid C. The final temperature of the liquid D. The mass of the liquid

Answer 1

The rate at which the temperature increases depends on -

D) the mass of the liquid

ΔQ = c M ΔΤ

ΔΤ/Δt does not depend on B) alone or C) alone nor does the rate of heating depend on A) time for which liquid is heated
