Application +4 | -1

Temperature of

100 \mathrm{gm}

water is changed from

0^{\circ} \mathrm{C}

3^{\circ} \mathrm{C}

in this process, heat supplied to water will be (specified heat of water

=1 \mathrm{~cal} \mathrm{~g}^{-1}{ }^{\circ} \mathrm{C}^{-1}

View answer and explanation

Correct option: C

less than

300 \mathrm{~cal}

Option C (less than

300 \mathrm{~cal}

) is correct because the density of water increases from

0^{\circ} \mathrm{C}

4^{\circ} \mathrm{C}

, resulting in negative work done by the system.
