Answer : The volume of gas occupy at
is, 1.25 L
Explanation :
Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
Mathematically,

where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:

Putting values in above equation, we get:

Therefore, the volume of gas occupy at
is, 1.25 L
Answer:
it is made up of rays of varying frequencies
Yes, Ionic bonds do not share electrons. Polar covalent bonds share electrons they just share them unevenly due to the polarity.
Conservation of energy
all of it should be transformed since the energy is convserved (neither destroyed nor created)
so answer is B
