# Question df087

I found: T_f=36.6°C

#### Explanation:

I found for Xenon:
$c =$specific Heat=158.32 "J"/("kg K")

Using the relationship for heat exchanged $Q$:

$Q = m c \Delta T$, where

$Q$ - heat absodrbed/released;
$m$ - the mass of the sample;
$c$ - the specific heat of the gas;
$\Delta T$ - the change in temperature, defined as ${T}_{f}$ - ${T}_{i}$,

$25.4 = \frac{12.1}{1000} \cdot 158.32 \cdot \left({T}_{f} - 23.4\right)$,
T_f=36.6°C#
