temperature equations

Question 1

what is the difference between latent heat and specific heat

Answer 1

Latent heat is the energy absorbed or released when a substance is undergoing a phase change. Specific heat is the quantity of heat required to raise the temperature of one Kg/grams of a substance by one degree Celsius (or one Kelvin) at a constant pressure.

Question 2

what is the formula for latent heat and what do the symbols mean

Answer 2

Q = M * L
Q = energy (J)
M = mass (kg)
L = the specific latent heat (J/kg)

Question 3

what is the formula for specific heat and what do the symbols mean

Answer 3

Q = mc∆T
Q = heat energy (Joules, J) 
m = mass of a substance (kg)
 c = specific heat (units J/kg∙K) 
∆ is a symbol meaning "the change in".
∆T = change in temperature (Kelvins, K)

Question 4

How many J are in a KJ

Answer 4

1000
