Answer 1

Answer:

Explanation:

The gas law used to solve the problems is Charles's law . It states with no pressure or energy change, the volume of an ideal gas is directly proportional to its temperature in Kelvin.

A gas occupies 547 L at 331K.

So its volume at 376K is

= 547 / 331 * 376

= 621.37 L

The gas law used to solve the problem is Boyle's law . It states with no temperature or energy change, the volume of an ideal gas is inversely proportional to its pressure.

A gas occupies 97 mL at 130 kPa.

So its volume at 225 kPa is

= 97 * 130 / 225

= 56.04 mL

Answer 2

#1

Apply charles law

$\\ \rm\Rrightarrow V1T2=V2T1$

$\\ \rm\Rrightarrow V2=\dfrac{V1T2}{T1}$

$\\ \rm\Rrightarrow V2=\dfrac{547(376)}{341}$

$\\ \rm\Rrightarrow V2=603.1L$

#2

Apply boyles law

$\\ \rm\Rrightarrow P1V1=P2V2$

$\\ \rm\Rrightarrow 130(97)=225V2$

$\\ \rm\Rrightarrow V2=56.04mL$
