How do you determine specific heat capacity of a liquid?
To determine the specific heat capacity of a liquid, you can use a calorimeter. By measuring the initial and final temperatures of the liquid when it absorbs a known quantity of heat, you can calculate the specific heat capacity using the formula Q = mcΔT, where Q is the heat absorbed, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the change in temperature.
The specific heat capacity of a liquid by an electrical heating method?
To determine the specific heat capacity of a liquid using an electrical heating method, you can measure the change in temperature of the liquid when a known amount of electrical energy is supplied. By using the formula Q = mcΔT (where Q is the heat energy supplied, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the temperature change), you can calculate the specific heat capacity of the liquid.
What are the substances that has low specific heat capacity?
Substances with low specific heat capacity include metals like aluminum and copper, as well as gases like helium and hydrogen. These substances heat up and cool down quickly compared to substances with higher specific heat capacities.
What is an example of low specific heat?
An example of a substance with low specific heat is metal, such as iron or aluminum. These materials heat up quickly when exposed to heat and cool down quickly as well, due to their low specific heat capacity.
Which liquid requires more time to increase in temperature by 5 degree?
A liquid with a higher specific heat capacity would require more time to increase in temperature by 5 degrees compared to a liquid with a lower specific heat capacity. This is because liquids with higher specific heat capacities can absorb more heat energy before their temperature rises.
Does aluminum have a higher specific heat capacity then lead?
No, lead has a higher specific heat capacity than aluminum. Lead has a specific heat capacity of around 0.128 J/g°C compared to aluminum's specific heat capacity of about 0.897 J/g°C.
Does aluminium have as high a specific heat capacity as iron?
No, aluminum has a lower specific heat capacity than iron. The specific heat capacity of aluminum is about 0.90 J/g°C, while iron has a specific heat capacity of about 0.45 J/g°C.

What is the specific heat capacity for the rocket fin?
The specific heat capacity of a material is the amount of heat energy required to raise the temperature of one unit mass of that material by one degree Celsius. The specific heat capacity for rocket fins will depend on the material they are made of, such as aluminum or titanium. For example, the specific heat capacity of aluminum is about 0.9 J/g°C.
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
Does Liquid ammonia have a higher heat capacity than liquid water?
No, liquid water has a higher heat capacity than liquid ammonia. Water has a high specific heat capacity due to its hydrogen bonding, which allows it to absorb and release heat more effectively than ammonia.
What is the Specific heat capacity of molten aluminum at 740 degree C?
The specific heat capacity of molten aluminum at 740°C is approximately 0.89 J/g°C. This value is specific to the temperature and state of the aluminum being molten.
What are the substances that has low specific heat capacity?
Substances with low specific heat capacity include metals like aluminum and copper, as well as gases like helium and hydrogen. These substances heat up and cool down quickly compared to substances with higher specific heat capacities.
In which temperature water has maximum specific heat capacity?
Water has the highest specific heat capacity at 25 degrees Celsius. This means that it can absorb or release a significant amount of heat before its temperature changes, making it an effective heat buffer.
What is an example of low specific heat?
An example of a substance with low specific heat is metal, such as iron or aluminum. These materials heat up quickly when exposed to heat and cool down quickly as well, due to their low specific heat capacity.
How many joules would be required to heat 0.5kg of aluminum?
The specific heat capacity of aluminum is 0.897 J/g°C. To calculate the energy required to heat 0.5kg of aluminum by a certain temperature change, you would use the formula: Energy = mass x specific heat capacity x temperature change If you have the temperature change, you can plug the values into the formula to find the total energy in joules.
