# A gas occupies 1676 mL at -85.1 °C and 225 mmHg. What will its temperature be when its volume is 838 mL at 3.5 atm?

##### 1 Answer

The new temperature would be 839 °C.

#### Explanation:

To solve this problem, we can use the **Combined Gas Laws**:

#color(blue)(bar(ul(|color(white)(a/a)(p_1V_1)/T_1 = (p_2V_2)/T_2color(white)(a/a)|)))" "#

We can solve this equation for

#T_2 = T_1 × p_2/p_1 × V_2/V_1#

In this problem,

∴

The new temperature is 839 °C.
