Calculate Total Amount Of Heat Required To Convert 100g Ice At 0в°C To Steam At 100в°C

Calculate the total amount of heat required to convert 100g ice at 0°C to steam at 100°C. (Specific latent … heat capacity of…

Answers:

Heat required to convert 100g ice at 00C to water at 00C

= Mass x Specific latent heat of fusion of ice

= 100 x 336 = 3600 J

Heat required to raise the temperature of 100g of water from 00C to 1000C

= Mass x Specific heat capacity of water x Rise in temperature

= 100 x 4.2 x (100 – 0) = 42000 J

Heat required to convert 100g water at 1000C to steam at 1000C

= Mass x Specific Latent heat of vaporisation of steam

= 100 x 2260 = 226000 J                         

Total heat required = 33600 + 42000 + 226000 = 301600 J
