How much enery is relased or observed when 1gm of ice at 0 cel turl into 1 gm of vapour at 100 cel |

Answer» ice at 0 ⁰C to turn into 1 GM of vapour at 100 ⁰C1) 1 gm of ice takes the latent heat of fusion to melt into water. heat energy needed = 1 gm * 334 Joules/gm = 334 J2) 1 gm of water heats up to 100°C as water heat energy needed = mass * specific heat * temperature difference = 1 gm * 4.18 J/gm/°C * 100°C = 418 Joules3) 1 gm of water at 100°C changes physical STATE into vapour heat energy needed = latent heat of vaporization = 1 gm * 2260 J/gm = 2260 Jtotal energy ABSORBED by the water = 334 + 418 + 2260 = 3, 012 Joules |
