Use the formula Q = m s T
given m = 5 kg
T - rise in temperature 50 deg
s = specific heat capacity 470 J/kg/K
So plug and we get Q = 117.5 kJ

What is the specific latent heat of fusion of mercury?
The specific heat temperature of mercury is 14 degrees Celsius. Comparably, the specific temperature of water is 417.9 degrees and air is 101 degrees.
How much heat energy is required to raise the temperature of 5 kilograms of cool from 20 degrees celto 220 degrees cel?
314j
5.10g sample of iron is heated form 36 degrees C to 75 degrees C the amount of energy is 89.5j the specific heat capacity of this sample of iron is?
The specific heat capacity of iron is 0,45 J/g.K.
How much energy would be needed to raise the temperature of a 5kg block of concrete by 10 degrees?
One needs to know the specific heat of concrete in order to answer this. q = mC∆T we know q = 52800 joules and the ∆T is 5 degrees. We do not know m (mass) or C (specific heat), so there are 2 unknowns.
What is minus 250 degrees to minus 450 degrees called on the Fahrenheit temperature scale?
There is no specific name for the range.
What property of a material tells you how much energy it can store?
Specific heat capacity tells you how much stuff energy can store. specific heat capacity is the amount of energy needed to raise the temperature of 1kg of a substance by 1 degrees celsius. water has a specific heat capacity of 4200 J/kg degrees celsius.
What are the units for mass what are the units for temperature?
Kilograms and Kelvin (or degrees Celsius).
What does it mean to say that a material has a high or low capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
What is the amount of heat required to change the temperature of 200.0 grams of aluminium to 10 degrees Celsius?
Q=m.c.Δt (m: mass, c: specific heat capacity, Δt :change in temperature)(specific heat capacity of aliminum is 0.90 J/K.g = 200 x 0.90 x 10 (if initial temperature is 0)(if not, then Δt=final temperature-initial temperature) =1800 Joules

So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is used to find the specific heat capacity of a substance?
The equation for specific heat is: C = q/temp. change x mass. C is a substance's specific heat, which is a constant for every substance. q is its heat capacity in joules, temp. change is the change in temperature in degrees Celsius, and mass is in grams.
What air temperature has the capacity to hold more water vapor 5 degrees or 11 degrees?
11 degrees.
What is the specific latent heat of fusion of mercury?
The specific heat temperature of mercury is 14 degrees Celsius. Comparably, the specific temperature of water is 417.9 degrees and air is 101 degrees.
Will the same mass of iron and water require the same amount of heat to increase their temperature the same number of degrees?
No, no. Of course not. The amount of heat Q required to increase the temperature of a body of mass m having specific heat capacity c through DO degrees celsius is given by: Q = mcDO Thus, the one with the higher specific heat capacity will require more heat energy.
What is the mass of a cubic meter of uranium when it has a temperature of 4 degrees Celsius?
19 050 kilograms
What is the average room temperature in kilograms?
The kilogram (kg) is a unit of mass, and cannot be applied to temperature. However, room temperature is generally regarded as 20 degrees Celsius, which is 68 degrees Fahrenheit, or 293 kelvins.
