Answer:
Ice melting is a physical change. Physical changes are changes which affect the form of a chemical substance, but not its chemical composition. Certain factors, such as, temperature, contribute to the melting of ice, but it will be classified as a physical change, because the number of molecules present in the water does not change.
Explanation:
Answer:
Volume = (0.62 m)^3
Explanation:

Answer:
The outside temperature is -45.8°C
Explanation:
When a gas keeps on constant its moles and its pressure, we can assume that volume will be increased or decreased as the T° (absolute T° in K).
V1 / T1 = V2 / T2
2.95L/298K = 2.25L / T2
(2.95L/298K ) . T2 = 2.25L
T2 = 2.25L . 298K / 2.95L
T2 = 227.2K
T°K - 273 = T°C
227.2K - 273 = -45.8°C
