In a science lab, a student heats up a chemical from 10 °C to 25 °C which requires thermal energy of 30000 J. If mass of object is 40 kg, specific heat capacity of chemical would be
  1. 25 J kg-1 °C-1
  2. 50 J kg-1 °C-1
  3. 75 J kg-1 °C-1
  4. 100 J kg-1 °C-1
Power is defined as
  1. p = W/t, where W is work and t is time
  2. p = t/W, where t is time and W is work
  3. p = W/d, where W is work and d is distance
  4. p = d/W, where d is distance and W is work
Amount of pressure of liquid increases with
  1. Volume
  2. Base area
  3. Mass
  4. Depth
