the heat capacity of glass--15points

1. Immerse the glass in a beaker containg water with known temperture (θ1 )

2. And then immerse the glass with temperture (θ1) in a beaker containg hot water with known temperture and mass (θ2 and M )

3. after one minutes, measure the temperture of the water (θ3)

Let the heat capacity of glass be C and the specific heat capacity of water is c,

Energy of water and energy of glass initially = Energy of water and energy of glass finally

M c θ2 + C θ1 = M c θ3 + C θ3

Then, C can be calculated

Remarks:
heat capacity 同 specific heat capacity 係唔同的

前者是　每一公斤和每一Ｋ的所改變能量
是 m c (dT) 中的 c

後者是　每一Ｋ的所改變能量
是 m c (dT) 中的 m c

K: 溫度單位
