Molar heat capacity (C_p ) of water at constant pressure is 75 JK ⁻¹ ~mol ⁻¹ . The increase in temperature (in K) of 100 ~g of water when 1 ~kJ of heat is supplied to it is

Options

  1. A2.4
  2. B0.24
  3. C1.3
  4. D0.13

Correct answer

A. 2.4

Step-by-step solution

Molar heat capacity is the amount of heat required to raise the temperature of 1 mole of a substance by 1^ C . aligned H & =n C_p T 1000 & = 100 18 75 T T & = 180 75 =2.4^ aligned
