To determine the specific heat capacity of water, we can follow these steps:
### Step-by-Step Solution:
1. **Understand the Definition**: The specific heat capacity (C) of a substance is defined as the amount of heat (Q) required to raise the temperature of 1 kg of that substance by 1 degree Celsius (or 1 Kelvin).
2. **Formula for Specific Heat Capacity**: The formula for specific heat capacity is given by:
\[

Some heat energy is given to 120 g of water and its temperature rises by 10 K. When the same amount of heat energy is given to 60 g of oil, its temperature rises by 40 K. The specific heat capacity of water is 4200 J kg- K^(-1) . Calculate : (i) the amount of heat energy in joule given to water, and (ii) the specific heat capacity of oil.
Equal volumes of water and alcohol when put in similar calorimeters take 100 sec and 74 sec respecively to cool from 50^(@)C to 40^(@)C . The thermal capacity of each calorimeter in numerically equal to the volume of either liquid. The specific gravity of alcohol is 0.8 if the specific heat capacity of water is 1 cal//gm , the specific heat capcity of alcohol will
Figure shown two adiabatic vessels, each containing a mass m of water at different temperature. The ends of a metal rod of length L, area of cross section A and thermal conductivity K, are inserted in the water as shown in the figure. Find the time taken for the difference between the temperature in the vessels to become half of the original value. The specific heat capacity of water is s. Neglect the heat capacity of the rod and the container and any loss of heat to the atmosphere.
