Specific heat capacity is the amount of energy or heat (q) required to raise the temperature of 1 gram of substance 1 degree Celsius. from the equation q = mc(Tf-Ti) q = energy / heat and is in joules (J) m = mass of in grams (look at Periodic Table for mass (g) per 1 mole of element) c = specific heat, for example water is 4.184 J/g*C Tf = Final temperature in *C Ti = Initial Temperature in *C

What is the equation for calculating how much heat energy (calories) transferred to or from a mass of water.?
The equation is q = mC∆T where q is the heat; m is the mass of water; C is the specific heat of water (1 cal/g/deg); and ∆T is the change in temperature.
How much heat is required to raise 70 kg of iron 10 degrees in celsius?
The formula to use is Q=mc∆T heat transfered=(mass)(specific heat)(change in temperature) Iron's specific heat is 0.46, mass is 70 kg, and the change in temp is 10. The equation will look like this: Q=(70)(.46)(10) Q=322kJ
What is a specific heat formula?
Q = mcΔT or Q=cpmΔTQ is the amount of heat needed to change the temperature of a substancem is the mass of the heated substancecp is the specific heat capacity (if this is what you're looking for, then the equation should be Q / mΔT = cp )ΔT (pronounced delta T) is the temperature difference; the difference in temperature before and after you applied the heatA very helpful PowerPoint: http://www.seaford.k12.de.us/es/smalley/ps%20unit%20lect/Heat%20and%20temperature.ppt
What is specific heat capacity and what does it measure?
Specific heat capacity(q) is the amount of heat needed to raise a tamperature of a body with mass of 1kg by 1K or 1 decree celcius. The formuale to calculate it is c(specific heat capacity) = Q/mass x change in temperature.
How do you find how much heat is gained in a specific heat problem?
q = C x m x (Tf-Ti), where q is heat, C is specific heat capacity, m is mass in grams, and (Tf-Ti) is change in temperature.
What does q mean in the equation q equals ml?
amount of heat energy
What variable represents specific heat in the equation Q mcT?
variable c
What variable represents specific heat in the equation Q equals mcT?
The variable c
What is the equation for calculating how much heat energy (calories) transferred to or from a mass of water.?
The equation is q = mC∆T where q is the heat; m is the mass of water; C is the specific heat of water (1 cal/g/deg); and ∆T is the change in temperature.
In the equation Q mcΔT c represents .?
The specific heat of the substance being heated.
In the equation Q mc and DeltaT c represents .?
Answer: Thermal Heat. Its Thermal somethingI just passed it and forgot the answer
For the specific heat capacity equation q equals m x C x Δt does change in temperature always have to be positive?
no

What is the formula for finding the mass in specific heat?
You just have to use algebra to manipulate the formula that you are used to. Q=mCpΔT, the formula you probably use most of the time, can be easily changed to solve for mass instead of heat (Q). You just divide both sides of the equation by Cp and ΔT, resulting in the equation Q/CpΔT=m.
What is the equation for specific equations?
Q = mc(delta)T Q = quantity of heat energy m = mass c = specific heat capacity different constant for each different substance (delta)T = difference in temperature (subtract high temp - low temp)
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.
Why is the triangle symbol in front of the T but not the Q in the equation Q equals m x T x C?
That equation is, q(Joules) = mass * specific heat ( symbol is C ) * (delta, a triangle) change in temperature That is to say delta means, Temperature Final - Temperature Initial q is a constant and not subject to change as temperature is
