How much energy needs to be supplie...

How much energy needs to be supplied to 150g of water at `100^(@)C` to convert it to steam at `100^(@)C` . `(L_(vap) = 540 cal//g)` .

Text Solution

Verified by Experts

Given m = 150g
L = 540 Cal / g
To find : Q = ?
Formula Q = mL
Solution : `Q = 150 xx 540`
` = 8100 cal`
Heat energy needed is 81000 cal .
