Sample JAMB UTME Physics 2020 questions

1. A tank contains water to a depth of 2.0 m. Taking the density of water as 1000 kg/m^3 and g as 10 m/s^2, what is the gauge pressure at the bottom?
  1. 20 000 Pa
  2. 2 000 Pa
  3. 5 000 Pa
  4. 200 000 Pa

Answer: A. 20 000 Pa

The gauge pressure is rho g h = 1000 x 10 x 2.0 = 20 000 Pa.

2. A temperature of 27 degrees Celsius is equivalent to approximately how many kelvins?
  1. 246 K
  2. 300 K
  3. 273 K
  4. 310 K

Answer: B. 300 K

Convert Celsius to kelvins by adding 273, so 27 + 273 = 300 K.

3. A 2.0 m metal rod has a linear expansivity of 1.2 x 10^-5 K^-1. How much does it lengthen when its temperature rises by 50 K?
  1. 0.12 mm
  2. 12 mm
  3. 1.2 mm
  4. 6.0 mm

Answer: C. 1.2 mm

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

4. A fixed mass of gas occupies a constant volume at 90 kPa and 300 K. What is its pressure when the temperature is raised to 400 K?
  1. 67.5 kPa
  2. 90 kPa
  3. 100 kPa
  4. 120 kPa

Answer: D. 120 kPa

At constant volume, pressure is proportional to absolute temperature, so P2 = 90 x 400/300 = 120 kPa.

5. How much heat is required to raise the temperature of 0.50 kg of water by 20 K? Take the specific heat capacity of water as 4200 J kg^-1 K^-1.
  1. 42 000 J
  2. 4 200 J
  3. 21 000 J
  4. 84 000 J

Answer: A. 42 000 J

Using Q = mc deltaT gives Q = 0.50 x 4200 x 20 = 42 000 J.
