How much energy is required to raise the temperature of 2 kg of iron from 20 C to 23 C to refer to the table of specific heat values apex?

How much energy is required to raise the temperature of 2 kg of iron from 20 C to 23 C to refer to the table of specific heat values apex?

m=2.00 kgc=449 J/kgoCΔT=23oC m = 2.00 kg c = 449 J/kg o C Δ T = 23 o C .

How much energy does it take to raise the temperature of a kilogram of water by 1 C?

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

How much energy is required to raise the temperature of 2.00 kg iron by 23.0 C the specific heat of iron is 0.449 JC?

Question: How much energy is required to raise the temperature of 2.00 kg iron by 23.0 degrees Celsius? The specific heat of iron is 0.449 J/(g degree Celsius) Answer is +20.7 kJ Please show steps!

How to calculate the energy required to raise the temperature?

To calculate the energy required to raise the temperature of any given substance, here’s what you require: The specific heat capacity of the material, #c# (which you can look up). This is the amount of heat required to raise 1 gram of that substance by 1°C. Here is a source of values of #c# for different substances:

What is the specific heat capacity of copper?

What is the specific heat capacity value of copper? The specific heat of copper is 385 J/kg K. You can use this value to estimate the energy required to heat a 100 g of copper by 5 °C, i.e., Q = m x Cp x ΔT = 0.1 * 385 * 5 = 192.5 J. What is the specific heat capacity value of aluminum?

How to calculate the specific heat capacity of a substance?

The formula for specific heat capacity, C, of a substance with mass m, is C = Q / (m ⨉ ΔT). Where Q is the energy added and ΔT is the change in temperature.

How to calculate the heat needed to heat 500 g of aluminum?

You can use this value to estimate the energy required to heat a 500 g of aluminum by 5 °C, i.e., Q = m x Cp x ΔT = 0.5 * 897* 5 = 2242.5 J.
