using the phase diagram for h20, what phase is water in at 1 atm pressure
and -5°c?

D as it is in the solid phase

Explanation:

Just a bit of steps here-

1. You take a look at the y-axis specifically at the 1 ATM part then assume what -5 would be on the x axis.

2. Connect them together and you would get the solid phase

3. Hence, the answer would be D

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
