Question

If heat is absorbed by water, what phase change occurs?

Answer 1

My answer would be B, Hope i helped u??

Answer 2

Ice=$H _{2} O$ in solid form 
water = $H _{2} O$ in liquid form
water vapor= $H _{2} O$ in gas form

If heat is absorbed by a liquid then it turns into a gas so B is the correct answer

when energy (heat) is added then solid becomes liquid and liquid becomes gas, in some rare cases a solid directly becomes a gas (sublimation) .
