Temperature

Question 1

Change in thermal energy - ∆Q

Answer 1

∆Q= mc ∆ theta
m- mass of substance
c- specific heat capacity of substance
theta- change in temp

Question 2

Amount of energy - Q

Answer 2

Q= Lm
L- latent heat of vaporization or fusion
m- mass of substance

Question 3

No of moles - n

Answer 3

n= N / N
N of moles = no of molecules / Avogadro’s constant

Question 4

No of moles n

Answer 4

N= m / Mr
m= mass of substance / molar mass
