Imagine you have a pot of water boiling on the stove. what is the water, and what is the steam that rises from the pot?
a. soiled, gas
b. liquid, gas
c. gas, liquid

the answer is B

Explanation:

bc the water is a liquid and the steam is the gas

b. liquid, gas

Explanation:

Water which is present in pot is liquid and steam that rises from the pot is gas.

Water between zero degree Celsius and 100 degree Celsius exists in liquid state. This is because in this range of temperature, water molecules are held together by weak hydrogen bonds. These hydrogen bonds keep water molecules together but these hydrogen bonds are not strong enough to condense them, so water molecules are constantly moving and exists in liquid state.

When heat is added to the system, energy of the water molecules are increased and they begin to move quickly. In this state, water molecules do not remain attracted to each other and eventually converted to gaseous state which is called steam.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

there are two significant figures.
