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).
