Thermal and gases exam style Qs

Question 1

A) Calculate, in K, the change in temperature of the gas during the compression that occurs between A and B.

b) Deduce whether the temperature of the gas changes during the compression from B to C.

Answer 1

A) charles law, V1/T1=V2/T2

=86K

B) P V / T = constant

prove that they are different values for the two points, conclusion: temp is not constant

Question 2

what is specific latent heat of fusion

Answer 2

Specific latent heat of fusion is the energy required to change 1 kg mass of material from the solid state to the liquid state or melt/fuse, without a change of temperature
