Thermal

Question 1

Boyle’s Law for changes in gas pressure at constant temperature

Answer 1

pressure1 (Pa) × volume1 (m3) = pressure2 (Pa)× volume2 (m3)
or
pressure (Pa) × volume (m3) = constant

P1V1 = P2V2
or
PV = constant

Question 2

Energy

Answer 2

(J)
mass (kg) × specific heat capacity (Jkg-1°C-1) × temperature change (°C)

E = mcΔT

Question 3

Thermal capacity

Answer 3

(J°C-1)
mass (kg) × specific heat capacity (Jkg-1°C-1)

C = mc

Question 4

Energy transferred

Answer 4

(J)
mass (kg) × specific latent heat (Jkg-1)

E = ml

Question 5

Expansion

Answer 5

(m)

linear expansivity (°C-1) × original length (m) × temperature rise (°C) Expansion = αlΔT
