in an experiment to verify CHARLES law,heat lose to the surroundings will not affect the results because charles law has no relationship with energy

答案話CORRECT

但係我覺得唔CORRECT架~ ENERGY一定有關 TEMPERATURE =ENERGY TRANSFER THX

更新1:

CHARLES LAW:V/T=V/T 有個TEMPERATURE在公式怎會無關 TEMPERATURE越高粒子的能量越大超級難題THXXXXXXXXXXXXXXXXXXXXX

更新2:

TEMPERATURE =ENERGY TRANSFER 搞錯 HEAT=energy transfer 不過TEMPERATURE越大 HEAT越大而且KE of molecules(collision is higher) 增加怎可說同能量無關 KE唔係能量??

更新3:

BUT!!!!!!!!!!!佢話同ENERGY無關架WOW~~~~~~~~~~

更新4:

邊有可能無關架 T增加KE增加 T減少KE減少明明就有關= = because charles law has no relationship with energy ???

更新5:

in an experiment to verify CHARLES law,heat lose to the surroundings will not affect the results >>>我覺得E個係正確,不過 because charles law has no relationship with energy >>>>E個我就唔明白 TEMPERATURE一定同ENERGY有關 charles law同TEMPERATURE有關即係同KE energy有關 THX

I think the statement is not well written. It doesn't bring out the physical concept precisely.

Charles Law applies under the condition that the pressure of the gas is held constant. As such, any change in volume brings a change in temperature. According to the first law of thermodynamics, there must an energy exchange with the environment.

The statement is best re-written to read as: ".... in an experiment to verify CHARLES law,heat loss to the surroundings will not affect the results because it is not the purpose of Charles Law to deal with any energy change."

1. TEMPERATURE越大 ENERGY越大
2. KE of molecules(collision is higher) 增加, Average distance to move by each molecules 增加
3. Distance 增加 in 3D, Volume 增加
4. Heat loss to surroundings, Temperature decrease, Volume decrease also at same ratio at constant pressure.
5. So, V/T is constant. That's Charles Law
