APPLICATION OF COMBINED GAS LAW
Combined gas law is a combination of Boyle's, Charles', and Gay-Lussac's Laws that expresses the relationship between pressure, temperature, and volume in a constant amount of gas (moles).
<u>Note:</u>
- In solving any problems related to Gas Law, it is important to remember that the standard unit measure for the temperature is always expressed in Kelvin (K). To do so, whatever the given temperature is (either °C or °F) you should convert them first so computation will be efficient.
- If the given is in °C, then use the formula
- And if °F,
So to answer your question, what is the new temperature in K, the new temperature is T2 = 269.176 K or 269.18 K
(Please see attached image for the solution).
ANSWER
C) (6,-8)
EXPLANATION
The equations are:
and
We substitute the first equation into the second equation to get:
We multiply through by 3 to get:
Group similar terms,
Divide both sides by 7 to get,
Put this value of x into the first equation to get;
