More essay examples on hydrogen rubric the amount of water wouldn’t change the temperature, so the heat capacity wouldn’t be changed the metal cooling off could change the heat capacity because the temperature wasn’t kept constant and would most likely lower the calculated value of the specific heat capacity. Heat of fusion specific heat capacity is the heat needed to raise the temperature of one gram (g) of a substance by one degree celsius specific heat capacity plays a role in the amount of heat absorbed or released by a substance because when there is high specific heat it takes a lot of energy to raise its temperature but when there is, low specific heat it does not take a lot of energy to. (2 marks) b) suggest two reasons why aluminium was chosen as the material for the body of the pot and not copper or leadphysics form 4 metal aluminium copper lead density / kgm-3 2700 8900 11300 specific heat capacity / jkg-1oc-1 900 390 130 a) state two advantages of using copper as the base of the pot.

The molar heat capacity is the heat capacity per unit amount (si unit: mole) of a pure substance and the specific heat capacity, often simply called specific heat, is the heat capacity per unit mass of a material occasionally, in engineering contexts, the volumetric heat capacity is used. Specific heat capacity, also called specific heat or thermal capacity, is defined as the amount of heat needed to raise the temperature of a substance by 1 degree just like the definition might suggest, the amount of heat needed will vary and depend on the substance. Published: fri, 09 mar 2018 samerah mansha aim the aim of this investigation was to measure the specific heat capacity (shc) of various different metals such as aluminum, iron and brass of different volumes to find out if they all have the same shc or different.
Aluminum oxide, al 2 o 3 ceramic properties alumina is one of the most cost effective and widely used material in the family of engineering ceramics the raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes. The specific heat capacity of aluminum is 897 j/gk what quantity of heat (in joules) is required to heat 150 grams al from 220 degrees celcius to 750 degrees celcius the key to solving this problem is knowing the specific heat capacity equation.
