a sample of ideal gas is originally at 40 degrees celsius. what is the final temperature of the gas if the volume is doubled and
Assoli18 [71]

Answer:

313 K or 40 degree celsius.

Explanation:

Initial , V_{i}=V_{0}

P_{i}=P_{0}

T_{i} =40+273=313K

Now, final

P_{f} =\frac{1}{2}P_{0}

V_{f} =2V_{0}

Combined  the ideal gas law

\frac{P_{i}V_{i}}{T_{i}}=\frac{P_{f}V_{f}}{T_{f}} \\\frac{P_{0}V_{0}}{T_{0}}=\frac{1}{2} \frac{P_{0}2V_{0}}{T_{f}} \\T_{f}=T_{0}\\T_{f}=313K

Therefore, the final temperature of ideal gas is 313 K.

Llana [10]

Answer:

Explanation:

Yes I agree with the statement .

When a person who is perfectly insulated from the earth , touches a Van de Graaff , his body acquires charge . when the hair acquires it, it stands out due to mutual repulsion . It is to be noted here that at pointed areas on a surface , there is larger accumulation of charge. Accumulation of charge is greater at hair tops .

It is also a general observation that when a bird sits on high tension wire , his feather stands out due to the same reason.
