Question

1 litre of water at 20 °C and 80 °C respectively are mixed together ,the temperature of the mixture will be *​

Answer 1

The temperature of water will be between 20 degree celcius and 80 degree celcius

Answer 2

Answer:

1 litre of water at 20 °C and 80 °C respectively are mixed together, the temperature of the mixture will be between 20°C and 80°C.

Explanation:

Given: 1 litre of water at 20°C is mixed with 1 litre of water at 80°C.

Calculation:

1 litre of water at 20°C is mixed with 1 litre of water at 80°C.

The volume of both are same and the heat will transfer from higher temperature water to the lower temperature water, i.e., from 80°C to 20°C.

Hence, 80°C temperature will decrease because of heat transferred to 20°C and the temperature of 20°C will increase.

Therefore, the temperature lies between 20°C to 80°C.
