At constant volume, you cool a sealed, air-filled can, and the pressure reduces by half. What happens in this situation? The num

ber of collisions per unit area doubles. The spaces between the gas molecules shrink. The temperature of the air inside reduces by half. Half of the gas leaks out.

Answer:

The correct answer to the question is

The temperature of the air inside reduces by half.

Explanation:

The relation to apply here is

(P₁×V₁)/T₁ = (P₂×V₂)/T₂

Thus we have at constant volume

P₁/T₁ = P₂/T₂

Therefore since the pressure reduces by half we have

then P₂ = 0.5 × P₁ or

P₁/T₁ = 0.5 × P₁/T₂ that is 1/T₁ = 0.5/T₂ or T₂ = 0.5 × T₁

The temperature of the air reduces by half

The above relationship is an example of Gay-Lussac's law which states that constant volume, the pressure of a given mass of gas is directly proportional to the temperature in kelvin. That is an increase in presure increases the temperature and a decrease in pressure causes an equivalent decrease in temperature

If an alloy is formed that is 50 mol% silver and 50 mol% gold, what is the karat number of the alloy?
Allisa [31]
Answer : 12 karat

Explanation : When pure gold is considered to be 24 karat then if its 50 mol% silver and 50 mol% silver then using karat scale calculation;

Karat/24 X 100 = 50 mol% (for gold) in alloy

So, Karat = (50 X 24) / 100 = 12 karat.

Hence the alloy will be of 12 karat.

A 1.85 kg textbook is sitting on a bookshelf 2.23 m above the floor. How much potential energy does it have?
neonofarm [45]

Answer:

\boxed {\boxed {\sf 40.4299 \ Joules}}

Explanation:

Potential energy is energy due to position. It is the product of mass, height, and acceleration due to gravity.

PE= m \times g \times h

The mass of the textbook is 1.85 kilograms. Assuming this is on Earth, the acceleration due to gravity is 9.8 meters per square second. The height is 2.23 meters.

  • m= 1.85 kg
  • g= 9.8 m/s²
  • h= 2.23 m

Substitute the values into the formula.

PE = 1.85 \ kg \times 9.8 \ m/s^2 \times 2.23 \ m

Multiply the first 2 numbers together.

PE=18.13 \ kg*m/s^2 *2.23 \ m

Multiply again.

PE= 40.4299 \ kg*m^2/s^2

  • 1 kilogram square meter per square second (1 kg*m²/s²) is equal to 1 Joules (J)
  • Our answer of 40.4299 kg*m²/s² is equal to 40.4299 J

PE= 40.4299 \ J

The textbook has <u>40.4299 Joules of potential energy.</u>

If I only want to make 500 mL of a 1.25% bleach solution, how many milliliters of bleach would I need? Show your work or explain
kiruha [24]

Answer:

  6.25 mL

Explanation:

1.25% of 500 mL is ...

  0.0125×(500 mL) = 6.25 mL

Since 1.25% of the 500 mL of solution is bleach, that's how much you need. That amount is 6.25 mL.
