Answer:
3) 670.7 °C (nearest tenth)
4) 818.2 torr (nearest tenth)
Explanation:
<h3><u>Question 3</u></h3>
<u />
<u>Charles's Law</u>

where:
= first volume
= second volume
= first temperature
= second temperature
Given:
First convert Celsius to kelvin:
Kelvin = Celsius + 273.15
⇒
= 10 + 273.15 = 283.15 K
Substituting the given values into the formula:




Converting kelvins back to Celsius:

Therefore, the final temperature will be 670.7 °C (nearest tenth).
<h3><u>Question 4</u></h3>
<u />
<u>Gay-Lussac's Law</u>

where:
= first volume
= second volume
= first temperature
= second temperature
Given:
= 760 torr-
= 27 °C
= 50 °C
First convert Celsius to kelvin:
kelvin = Celsius + 273.15
⇒
= 27 + 273.15 = 300.15 K
⇒
= 50 + 273.15 = 323.15 K
Substituting the given values into the formula:





Therefore, the new pressure is 818.2 torr (nearest tenth).
