PHYSICS $2$ COLLEGE Get a percent answer for part A and a numerical answer for B with a good explanation for a thumbs up

$($a$)$ Starting at room temperature, you repeatedly put small increments of energy into a

fixed volume of this gas, and as you do$,$ you measure the response of its temperature. The

temperature increase due to the introduction of a fixed amount of energy is predictable for a

long time, until rather suddenly it is not the same as before. Is the new temperature change

greater or less than before, and by what percentage has this effect changed?

$($b$)$ If you continue to put energy into this gas, will the phenomenon you witnessed in $($a$)$

occur again? How many times? Explain.
