Answer:

Option D. 1092K

Explanation:

T1 = 273K

V1 = V

P1 = P

V2 = 2V( i.e double of original volume)

P2 = 2P (i.e double of original pressure)

T2 =?

P1V1/T1 = P2V2/T2

PV/273 = 2P x 2V / T2

Cross multiply to express in linear form

PV x T2 = 273 x 2P x 2V

Divide both side by PV

T2 = (273 x 2P x 2V) / PV

T2 = 273 x 2 x 2

T2 = 1092K

In a given substance, as the temperature of a substance increases, the volume of that substance _____.

Molodets [167]

Answer:

C: increases

Explanation:

Temperature is directly proportional to volume. If the temperature of a substance increases, the volume also increases. If the temperature decreases the volume also decreases.

According to Charles's law "the volume of fixed mass of gas varies directly as its absolute temperature if the pressure remains constant". Although this is an ideal gas law, it is also applicable to most substances.

As the temperature is raised, the volume also behaves proportionally that way.

If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?

Darina [25.2K]

The question is incomplete, here is the complete question:

A bottle of rubbing alcohol having aqueous solution of alcohol contains 70% (v/v) alcohol. If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?

Answer: The amount of water present in the given bottle of rubbing alcohol is 283.8 mL

Explanation:

We are given:

Volume of bottle of rubbing alcohol = 946 mL

70% (v/v) alcohol solution

This means that 70 mL of rubbing alcohol is present in 100 mL of solution

Amount of water present in solution = [100 - 70] = 30 mL

Applying unitary method:

In 100 mL of solution, the amount of water present is 30 mL

So, in 946 mL of solution, the amount of water present will be = $\frac{30}{100}\times 946=283.8mL$
