The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens
poizon [28]

Answer:

<u>It increases by a factor of four</u>

Explanation:

Boyle's Law : At constant temperature , the volume of fixed mass of a gas is inversely proportional to its pressure.

pV = K.......(1)

pV = constant

Charles law : The volume of the gas is directly proportional to temperature at constant pressure.

V = KT

or V/T = K = constant ....(2)

Applying equation (1) and (2)

\frac{PV}{T}=K

\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}

According to question ,

T2 = 4 (T1)

V2 = V1

Put the value of T2 and V2 , The P2 can be calculated,

\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{1}}{4T_{1}}

V1 and V1 cancel each other

T1 and T1 cancel each other

We get,

P1=\frac{P2}{4}

or

P2 = 4 P1

So pressure increased by the factor of four

10g of an oxide of copper contains 8.882g of copper. what is empirical formula of the copper oxide
-BARSIC- [3]

Answer:

Mass of copper oxide: 10g

Mass of copper: 8.882g

Mass of oxygen: 1.118g

                                                                <u> Cu</u>               <u>O</u>

                                                              8.882           1.118

Divide by A_{r}                                   8.882÷63.5       1.118÷16

                                                               0.14             0.07

Divide by the lowest number          0.14/0.07       0.07/0.07

                                                                  2                  1

Check the ratio now, Cu has 2 atoms and O has 1 atom .

The formula is Cu_{2} O
