At 25°C, gas in a rigid cylinder with a movable piston has a volume of 145 mL and a pressure of 125 kPa. Then the gas is compres
natta225 [31]

Answer:

(4) 230 kPa

Explanation:

The temperature is constant, so the only variables are pressure and volume.

We can use Boyle’s Law.

p_{1}V_{1} = p_{2}V_{2}

Divide both sides of the equation by V_{2}.

p_{2} = p_{1} \times \frac{V_{1}}{ V_{2}}

p_{1} = \text{145 kPa}; V_{1} = \text{125 cm}^{3}}

p_{2} = ?; V_{2} = \text{80. cm}^{3}

p_{2} = \text{145 kPa} \times \frac{\text{125 cm}^{3}}{\text{80. cm}^{3}} = \textbf{230 kPa}
