Class X

As volume is inversely proportional to pressure, we can conclude that
  1. p1V2 = p2V1
  2. p2/V2 = p1V1
  3. p1V1 = p2V2
  4. p1V1 = p2/V2
 In a typical hydraulic press, a force of 20 N is exerted on small piston of area 0.050 m². force exerted by large piston on load if it has an area of 0.50 m² will be
  1. 200 N
  2. 100 N
  3. 50 N
  4. 10 N
Melting point of tin is
  1. 32 °C
  2. 132 °C
  3. 232 °C
  4. 332 °C
Air trapped inside a single-piston-cylinder exerts a pressure of 760 mmHg. If its volume is increased at a constant temperature such that final pressure is equal to 507 mmHg then increase in volume is equal to
  1. 0.2
  2. 0.3
  3. 0.4
  4. 0.5
As collision of particles in liquids and gases is lesser, so flow of kinetic energy would be
  1. Faster
  2. Slower
  3. Normal
  4. Zero
