Answer:
It will increase the kinetic energy of gas particles and hence gas will expand.
Explanation:
According to law, there is direct relationship between temperature (thermal energy) of gas and it's volume. When the pressure of gas is held constant and it's temperature increases then the volume of gas also gets increases.
When the temperature ( thermal energy) of gas increases then the kinetic energy of particles of gas also gets increases due to which particles start to collide with the wall of container and with themselves as well which in turn causes gas to expand.

Answer:
A) The shared electrons in C-O bonds spend less time close to the carbon nucleus than the shared electrons in C-H bonds.
Explanation:
The electronegativity from H is 2.2, from C is 2.55 and from O is 3.44. This property is the measure of the attractive force between an atom and a pair of electrons.
So, the difference of electronegativity of H and C is smaller than the difference between O and C. Because oxygen is more electronegative, the electrons stay close to it in the bond C=O. So carbon has a partial positive charge in that bond. For the bond C-H, the shared electrons stay closes to carbon.
