CSEC Physics · May/June 2009 · Paper 2 · Question 6(b)
A physics student was provided with 25 g of ice to convert to steam. Specific heat capacity of ice = 2 x 10³ Jkg⁻¹K⁻¹, Specific heat capacity of water = 4.2 x 10³ Jkg⁻¹K⁻¹, Specific latent heat of vaporisation of water = 2.3 x 10⁶ Jkg⁻¹, Specific latent heat of fusion of ice = 3.4 x 10⁵ Jkg⁻¹.
How much heat is needed to change this 25 g of ice at 0° C to steam at 100° C?
