Answer:
The high specific heat capacity of water means that it takes much more energy to raise the temperatures of water by one (1) degree than land. This means that on a hot sunny day, land temperatures would increase dramatically while ocean temperatures would only rise slightly.

Answer:
B. A worker should not feel air moving around the chemical hood.
Explanation:
Hello!
In this case, since chemical hoods are used to remove the hazardous vapors given off by volatile chemicals, the idea is that the workers do not get in contact, in anyway, with those vapors as they can affect their health and safety at the laboratories.
It means that options A and C are ruled out because they describe an scenario in which the worker is in contact with the vapors and also because the vapors are removed via a fan system that withdraws the vapors.
Therefore the correct option is B. A worker should not feel air moving around the chemical hood.
Best regards!
Answer:
7.20 atm
Explanation:
Since the gas remains at constant temperature, we can solve this problem by using Boyle's Law, which states that:
"For a constant mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:
where
p is the pressure of the gas
V is the volume
The equation can be also rewritten as:
where in this problem, we have:
is the initial pressure of the gas
is the initial volume of the gas
is the final volume of the gas
Solving for p2, we find the final pressure:
