Given the law of conservation of energy, what happens when a 200°c iron bar is placed in thermal contact with a 30°c block of wood?
o a
energy leaves the iron bar and enters the wood until the temperatures are equal,
ob
energy leaves the wood and enters the iron bar until the temperatures are equal.
o
c.
all the energy from the iron bar is transferred to the wood.
o
d.
all the energy from the wood is transferred to the iron bar.

The correct answer is A Energy leaves the iron bar and enters the wood until the temperature are equal.

Explanation:

According to the law of conservation of energy or the first law thermodynamics energy neither be created nor destroyed, energy is transferred from one form to another form.

        Here iron bar is placed in wood block energy is transferred from iron bar to wood until the temperatures are equal.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
