H = m s t
H - heat energy in joule
m- mass of the body in kg
s - specific heat capacity J / kg / K
t - the temperature difference may be a rise or fall in K

What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What is specific heat capacity equation?
Quantity of Energy= mass x temperature change x specific heat capacity For example: Find the amount of energy needed to raise the temperature of 0.20 kg of lead by 15 degree Celsius if the specific heat capacity of lead is 0.90 J/g degree Celsius. Answer: J=200g x 15 degree Celsius x 0.90 J/g degree Celsius = 2700 J
In which temperature water has maximum specific heat capacity?
The specific heat capacity of water does not change much within-phase (ie, as a solid it has one specific heat capacity, as a liquid/gas it has another)
What is the specific heat constant of oxygen?
heat constant = mass * specific heat capacity * temperature change
What does it mean to say that a material has a high or low specific heat 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.
For the specific heat capacity equation q equals m x C x Δt does change in temperature always have to be positive?
no
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
Effect of temperature on specific heat of material?
The effect of temperature on specific heat of material is referred to as specific heat capacity.
What is specific heat capacity equation?
Quantity of Energy= mass x temperature change x specific heat capacity For example: Find the amount of energy needed to raise the temperature of 0.20 kg of lead by 15 degree Celsius if the specific heat capacity of lead is 0.90 J/g degree Celsius. Answer: J=200g x 15 degree Celsius x 0.90 J/g degree Celsius = 2700 J
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.
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.
In which temperature water has maximum specific heat capacity?
The specific heat capacity of water does not change much within-phase (ie, as a solid it has one specific heat capacity, as a liquid/gas it has another)
What two things affect energy?
Its temperature and its specific thermal capacity
How much energy must be added to a 2kg piece of wood with a specific heat capacity of 1760 JkgoC to increase its temperature from 10oC to 50oC?
Its 900 joules to raise the temperature of 1Kg of the substance by a degree, and we have 2Kg, to heat out sample we need 1800 J to raise the temperature by one degree celsius. we need to heat the sample by 40 degrees and if we need 1800 J per degree then 40 x 1800 = 72000 J needed. Or 72KJ
What does the amount of energy needed to heat water depend on?
The equation Q=mcΔ t calculates the amount of energy for a body of mass to raise a unit temperature per unit mass. The specific heat capacity of water is 4.19 J/g°C which means that it takes 4.19 J to raise 1 g of water to 1°. The specific heat capacity also depends on what the surrounding temperature is. 4.19 J/g°C is the specific heat capacity at room temperature. Since temperature is the measurement of the average kinetic energy of the particles, the motion of particles in water affects the specific heat capacity which ultimately affects how much energy is needed to heat up water.
Dimensional formula for heat capacity and specific heat capacity?
heat capacity- ML2T-2K-1 Specific Heat Capacity-M0L2T-2K-1
What is the specific heat constant of oxygen?
heat constant = mass * specific heat capacity * temperature change
