C) An aluminium with a mass of 500 g has been heated from 31 °C to 80°C. Then the aluminium plate was placed into a container that has 700 g of liquid Y at a
temperature of 15 °C. Calculate:
Sebuah plat aluminium berjisim 500 g telah dipanaskan dari 31°C kepada 80
°C. Selepas itu, plat aluminium itu dimasukkan ke dalam bekas yang
mengandungi 700 g cecair Y pada suhu 15 °C. Kirakan:
i. The quantity of heat that is used to heat the 500 g aluminium plate. (Specific
heat capacity of aluminium is 950 J/kg°C)
