Thermodynamics

If the gas is heated at a constant volume, the incoming heat is converted to external work.

Apabila gas pada volume tetap dipanaskan, maka kalor yang diterima itu akan diubah menjadi usaha luar

• True

• False

1The heated gas molecules' kinetic energy will increase.

Energi kinetic molekul gas yang dipanaskan akan bertambah.

• True

• False

When an ideal gas is compressed adiabatically, its internal energy increases.

Energi dalam sebuah gas ideal akan bertambah jika dimampatkan secara adiabatic.

• True

• False

The temperature of an ideal gas is directly proportional to its energy.

Energi dalam gas ideal berbanding lurus dengan suhu gas.

• True

• False

Work is not done by an ideal gas that grows its volume isobarically.

Gas ideal yang melakukan pengembangan volume secara isobaric tidak melakukan usaha

• True

• False

When an ideal gas expands, the amount of work it does is proportional to the change in gas pressure.

Usaha yang dilakukan oleh gas ideal Ketika mengembang sebanding dengan perubahan tekanan gas

• True

• False

When applying the first law of thermodynamics to a system, when is heat a positive quantity?

• when the system does work

• when the system absorbs heat

• when no work is done either on the system or by the system

• when the system has work done on it

• when the system loses heat
