Question

2. An immersion heater is placed in crushed ice at - 40 C. contained in a perspex jar,
formed. If the power of the heater is 200 W and it is switched on for 3 min. and 20 s, calculate the in
of ice. SHC of ice - 2.1 Jg and latent heat of ice - 336jg​

Answer 1

An immersion heater is placed in crushed ice at – 40°C, contained in a perpex jar, such that water at 50°C is formed. If the power of heater is 200 W and it is switched on for 3min. and 20s. Calculate the initial mass of ice S.H.C. of ice – 2.1Jg-1°C-1 and latent heat of ice = 336Jg-1Read more on Sarthaks.com - https://www.sarthaks.com/267828/an-immersion-heater-is-placed-in-crushed-ice-at-40c-contained-in-a-perpex-jar
