Steam at 100^(@)C is passed into 1.1 kg ...

Steam at `100^(@)C` is passed into `1.1 kg` of water contained in a calorimeter of water equivalent `0.02kg` at `15^(@)C` till the temperature of the calorimeter and its content rises to `80^(@)C`. What is the mass of steam condensed? Latent heat of steam = `536 cal//g`.

A

`0.130`

B

`0.065`

C

`0.260`

D

`0.135`

Text Solution

Verified by Experts

The correct Answer is:
D
Heat lost = Heat gained
` m_("steam") xx 540 = 1100 xx 1 xx (80-15)+20xx 1 xx (80-15)`
`therefore ` mass of steam condensed = `0.13` kg
