Sample JAMB UTME Physics 2019 questions

1. A metal rod is 2.0 m long at 20°C. If its linear expansivity is 1.2 x 10^-5 K^-1, how much does its length increase when its temperature rises by 50 K?
  1. 1.2 mm
  2. 0.12 mm
  3. 12 mm
  4. 2.4 mm

Answer: A. 1.2 mm

The increase is alpha L deltaT = 1.2 x 10^-5 x 2.0 x 50 = 0.0012 m, or 1.2 mm.

2. A fixed mass of gas occupies 0.020 m^3 at 27°C. If it is heated at constant pressure to 127°C, what volume will it occupy?
  1. 0.015 m^3
  2. 0.0267 m^3
  3. 0.0333 m^3
  4. 0.020 m^3

Answer: B. 0.0267 m^3

At constant pressure V/T is constant, so V2 = 0.020 x 400/300 = 0.0267 m^3.

3. A 0.50 kg metal block of specific heat capacity 400 J kg^-1 K^-1 receives 30,000 J of heat. By how many kelvins does its temperature rise?
  1. 75 K
  2. 120 K
  3. 150 K
  4. 300 K

Answer: C. 150 K

Using Q = mc deltaT gives deltaT = 30000/(0.50 x 400) = 150 K.

4. How much heat is required to melt 0.20 kg of ice at 0°C if the specific latent heat of fusion of ice is 3.36 x 10^5 J kg^-1?
  1. 6.72 x 10^3 J
  2. 1.68 x 10^5 J
  3. 3.36 x 10^5 J
  4. 6.72 x 10^4 J

Answer: D. 6.72 x 10^4 J

The melting heat is Q = mL = 0.20 x 3.36 x 10^5 = 6.72 x 10^4 J.

5. A vacuum flask has an evacuated gap between its inner and outer walls. Which modes of heat transfer are mainly reduced by this gap?
  1. Conduction and convection
  2. Radiation only
  3. Convection and radiation only
  4. Conduction and radiation only

Answer: A. Conduction and convection

The vacuum contains too few particles for conduction or convection, while the flask's reflective surfaces reduce radiation.
