Question

The temperature of 10 kg of a substance rises by 55oC when heated. Calculate the

temperature rise when 22 kg of the substance is heated with the same quantity of heat.

Answer 1

Given :

The temperature of 10 kg of a substance rises by 55oC when heated.

To Find :

The temperature rise when 22 kg of the substance is heated with the same quantity of heat.

Solution :

We know, change in temperature when heat is given to object is given by :

`\Delta H = m S\Delta T`

It is given that same amount of heat is given in both the cases also the substance is same.

So,

`M_1 S \Delta T_1 = M_2 S \Delta T_2\\\\10* 55 = 22 * \Delta T_2\\\\\Delta T_2 = 25^o\ C`

Hence, this is the required solution.
