The state of matter that is most compressible is gases because it fits in anything it's put in
Yes this is know as the c value. It is usually used in q=mc change in temperature
To solve this problem, we establish the general energy balance:
ΔE = ΔU + ΔKE + ΔPE
ΔE = Q + W
Q + W = ΔU + ΔKE + ΔPE
In this case, ΔKE and ΔPE are both zero or negligible.
Given:
m = 33.0 grams of CO2
Tsub = 77 K
P = 1 atm
ΔE = Q + W
ΔE = mCpΔT + ΔPV
solve for mCpΔT, find the value of Cp for CO2, then solve for Q. Next, solve for W using the ideal gas law. Add the two values and that will be the value of the delta E.

Given
40 °C measurement
Required
The percent error
Solution
% Error : difference between the theoretical value and the actual value
or
% Error : Absolute Error / Accepted Value
Absolute Error = Measured Value - Accepted Value
% Error for Chemistry student :
1. Subtract the measurement value with the accepted value
= 40 °C - 43.2 °C
= -3.2 °C
2. Divide by the accepted value, and multiply by 100
= |-3.2/43.2| x 100%
= 7.4%
