What means that a large amount of energy is required to change the waters temperature?
Specific heat
Would substances with high specific heat capacity also have high temperatures?
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE THE TEMPERATURE.
What metal will have the highest temperature with specific heat of aluminum 0.215 copper 0.092 and silver of 0.057?
I would like to start off by saying that: Energy absorbed by metal = mass of metal x specific heat capacity of metal x change in temperature of the metal If the same amount of energy is given to all three metals, there would be the highest temperature increase in the metal with the lowest specific heat capacity. Therefore, Silver would be the answer.
An increase in the average kinetic energy of a sample of copper atoms occurs with an increase in what?
Temperature
Why does the amount of water affect time it takes to boil?
The basic formula which describes the energy required to raise the temperature of a substance is ΔE=mcΔθ. where: ΔE = Difference in energy m = mass of the substance c = specific heat capacity of the substance Δθ = change in thermodynamic temperature without any calculation, it is clear that if the change in temperature is the same (i.e. from room temperature to boiling point); and the specific heat capacity is the same; the more of the substance that is being boiled; the more energy is required. If the device which is boiling the substance is at a constant power, whether it be a burner or a kettle, the more energy required to boil the substance, the more time it will take to boil so long as the power is held constant.
What is the significance of heat capacity?
The specific heat of a substance allows us to calculate the amount of heat energy required to change its temperature. Water has a specific heat nearly 11 times great than copper, therefore, water will take 11 times more energy to heat. Also water heats slowly and copper heats and cools rapidly.
What means that a large amount of energy is required to change the waters temperature?
Specific heat
Will concrete brick aluminum or copper take most energy to increase its temperature?
Whichever of them has the lowest specific heat capacity will take the least energy to raise its temperature, and whichever has the highest specific heat capacity will take the most energy.
When 90 kJ is removed from a 2-kg copper bar its temperature drops from 200C to 85C. The specific heat of copper is?
You are supposed to divide the energy by the product of (mass x temperature difference).
How does temperature relate to amount of energy present in a substance?
Higher temperature means greater energy content compared to a lower temperature. The energy required to change the temperature is proportional to the mass of the system, the specific heat capacity, and the temperature change.
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is specific latent of fusion?
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
If A 2000W electric heater supplies energy to 0.5kg copper kettle containing 1kg of water. calculate time taken to raise the temperature by 10 degree?
You can use the fact that the heat required is equal to mass x (temperature difference) x (specific heat). In this case, you have to do the calculation separate for the copper and water, and add the results up.Once you have the number of joules required, divide that by the power (note: watt = joules/second), to get the time required (in seconds).
The specific heat of the material is?
specific heat content is calculated by the joules of energy required to change the temperature of one cubic centimeter of the material 1 degree Celsius.
What is specific latent heat of vaporisation?
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?
Kilowatts is a unit of energy rate, while the temperature required to raise a specific volume of water by a specific amount of degrees is a unit of energy, not energy rate. The question cannot, therefore, be answered as stated. Please restate the question.
