Embibe Experts Solutions for Chapter: Thermal Properties of Matter, Exercise 1: Exercise 1

On the Celsius scale the absolute zero of temperature is at

Select correct statement related to heat

Assertion: Water is considered unsuitable for use in thermometers.

Reason: This is due to small specific heat and high thermal conductivity.

If $H_C,H_K$ and $H_F$ are heat required to raise the temperature of one gram of water by one degree in Celsius, Kelvin and Fahrenheit temperature scales respectively then:

In an experiment with a continuous flow calorimeter, an input power of $50 W$ produced a rise of $50°\mathrm{C}$ in the liquid. When the power was tripled, the same temperature rise was achieved by making the rate, of flow of liquid $n$ times its initial value. If the power lost to the surrounding in each case is $25 W$, value of $n$ is

Heat required in converting $1 \mathrm{g}$ of ice at $-10°\mathrm{C}$ into steam at $100°\mathrm{C}$ is

The water equivalent of $20 \mathrm{g}$ of aluminium (specific heat $0.2 \mathrm{cal} {\mathrm{g}}^{-1}{{}^{\circ }\mathrm{C}}^{-1}$), is
