Question

question 19
the temperature of a 250. ml sample of gas increases from 150. k to 450. k. what is the final volume of the sample of gas, if the pressure in the container is kept constant?

1. ml
2. ml

1170 ml

1. ml

0.00474 ml

Explanation:

Step1: Identify the gas law

Since pressure is constant, use Charles's Law: $\frac{V_1}{T_1}=\frac{V_2}{T_2}$

Step2: Substitute the values

Given $V_1 = 250$ mL, $T_1=150$ K, $T_2 = 450$ K. Rearrange for $V_2$: $V_2=\frac{V_1\times T_2}{T_1}$

Step3: Calculate

$V_2=\frac{250\times450}{150}= 750$ mL

Answer:

1. mL
