Answer:
C. The tea cools to room temperature, the ice cream melts and warms to room temperature.
Explanation:
The tea's temperature was higher than room temperature. The ice cream's temperature was lower than room temperature. After some time, both items will become room temperature, which results in cooling and melting.
Answer:
V₂ = 1518L
Explanation:
-Using combined gas law:

<em>Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
<em>Initial states:</em>
P₁ = 743 torr
V₁ = 975L
T₁ = 30°C + 273.15K = 303.15K
P₂ = 375 mmHg = torr
V₂ = Our incognite
T₂ = -35°C + 273.15K = 238.15K
Replacing:

<h3>V₂ = 1518L</h3>
