heat is supplied at a steady rate of 800 joules per minute to 100g of a solid substance in an insulated container. the temperature of the substance first rises steadily to -5°c to 25°c in 3 minutes and remains constant at 25°c for 35 minutes. it again rises steadily to 175°c at a rate of 6 degree per minute and remains constant at 175°C for another 2 minutes during which the mass decreases by 2g
1) use the info above to sketch the temperature variation of the substance with time also calculate for the substance it's
2) specific heat capacity
3) specific latent heat of fusion
4) specific latent heat of vaporization?
