is it the substance which has higher specific heat capacity?WHY??

✔ 最佳答案
E=mcΔT
既然 mass 同 temperature 都係一樣..
咁specific heat capacity自然就吸多o的energy..

佢地兩個一齊heat up

咁佢地吸既energy一定系一樣既

完完全全吾關個specific heat capacity事既

specific heat capacity吾同...只系會影響到佢地既溫度會有不同!!!!!!!!!!!!
參考: 吾明在問吧@@"

如果兩件物件係擺埋一齊... change in temperature都一樣既話
就係有高D specific heat capacity既物件.. 因為E= mc(change in temp)

如果分開.. 兩件物件既溫度不同
咁Energy gain就一樣.. P = E/t (from the heater)
