On a winter day with a temperature of - 10°C, 500g of snow (water ice) is brought inside where the temperature is 18 °C. The snow warms, then melts to water, and then warms to room temperature. What is the total amount of heat energy absorbed by the snow in this process?

Mass of ice m = 500g =.5 kg

Heat required to raise the temperature of ice by 10 degree

= mass of ice x specific heat of ice x change in temperature

=.5 x 2093 x 10 J

10465 J

Heat required to melt the ice

= mass of ice x latent heat

0.5 x 334 x 10³ J

167000 J

Heat required to raise its temperature to 18 degree

= mass x specific heat of water x rise in temperature

=.5 x 4182 x 18

=37638 J

Total heat

=10465 + 167000 + 37638

=215103 J
