How Is Energy Calculated for a Temperature Increase in Neon Gas?

[truckerron1]

i have 3 questions that i need help with

Consider 180 g of neon gas. How much energy would it have to absorb to experience a temperature increase of 12 K?

Construct a PV diagram for each of the following. (a) A gas begins with a volume of 14 L under pressure of 3 atm. The gas first undergoes an isobaric compression to a volume of 6 L. Next, the gas experiences an isothermal expansion back to a volume of 14 L. (b). A gas undergoes a cyclic process consisting of two isochoric processes and two isobaric processes.

A particular engine having efficiency 27% operates at temperature 420C. What is its highest possible exhaust temperature?

thanks ron

I will just help you with the first question.
Consider this formula:

$$Q = m.c.dT$$

m= 180 g
c= ? -> you have to check on a table
dT = 12 K

Now, it's up to you.
