zaharov [31]

Answer:

1.84 atm

Explanation:

P2=V1P1/V2

Temp is irrelevant because it is constant, so all you have to do is rearrange the ideal gas law.

You can check this by knowing P and V at constant T have an inverse relationship and therefore makes this the correct answer.

- Hope that helps! Please let me know if you need further explanation.

If 1000. mL of water freezes, which of the following is a reasonable approximation for the volume of the resulting ice?
Fudgin [204]

Answer:

If 1000. mL of water freezes, which of the following is a reasonable approximation for the volume of the resulting ice?

Group of answer choices

1000. mL

961 mL

1040 mL

Explanation:

Ice is fewer denser than water.

The reason is the volume occupied by the same mass of ice with water is more than the volume occupied by water. Ice has more empty space within it.

Due to this reason, ice floats on water.

When 1000ml of water freezes to ice then its volume is greater than water.

Among the given options the correct answer is 1040 mL .
