If the humidity of the room is low, the water that contacts the air directly could evaporate and takes some energy from the bulk thus decreasing its temperature steadily. This allows the water to have a lower temperature.
If the container has heat insulation, the rate of temperature drops will decrease too. Water specific heat is higher than the air, so it will need much more energy to increase water temperature.
Answer:
q = mC∆T
q = (50 g)(4.184 J/g/deg)(10 deg)
q = 2092 J = 2.09x10^3 J
That's how it's done.

Answer:
a. 916.95K is final temperature of the gas
b. 3667.8K
Explanation:
a. We can solve the temperature of a gas when the volume is expanded three times using Gay-Lussac's law:
P₁T₂ = P₂T₁
<em>Where P is pressure,</em>
<em>And T is absolute temperature of 1, initial states and 2, final states of the gas.</em>
<em />
Initial pressure is 6.60 atm, initial absolute temperature is 32.5°C + 273.15K = 305.65K. Final pressure is three times initial pressure = 6.60atm*3 = 19.8atm.
Solving for final temperature:
P₁T₂ = P₂T₁
6.60atm*T₂ = 19.8atm*305.65K
T₂ =
916.95K is final temperature of the gas
<em />
b. Charle's law is the gas law that relates changes in volume and temperature of a gas:
V₁T₂ = V₂*T₁
If the volume is quadrupled: V₂/V₁ = 4:
T₂ = 4*916.95K
T₂ = 3667.8K
A and B. note/ a chemical reaction is either
acid + base
carbonate + base
metal + base.
