The temperature of a piece of unknown metal with a mass of 18.0 g increases from 25.0 degrees C to 40 degrees C when the metal absorbs 124.2 J of heat What is the specific heat of the unknown metal?
Without stating units, it is impossible to answer this question accurately. However, the equation you would need is q=mc∆T, where q is the heat flow (the 53.0 listed, likely Joules), m is the mass of the unknown metal (11.1, likely grams), c is the specific heat of the metal (the unknown you need to solve for), and ∆T is the change in temperature of the metal (24.1-13.0, likely Celcius). Rearranged to solve for specific heat, the question is c=q/m∆T.
How much heat is liberated (in kJ) from 252 g of silver when it cools from 89.5 C to 26.3 C?
To answer this question, you need to know the heat capacity (C) for silver (Ag). It happens to be 0.240 J/g/deg. Then you can use the formula q = mC∆T where q = heat; m = mass; C = sp.heat cap; ∆T = change in temp. q = (252 g)(0.240 J/g/deg)(63.2 deg) = 3822 Joules
What is specific heat of a substance if 1560 cal are required to raise the temperature of a 312g sample by 15 degrees C elsius?
q = m x C x ΔT q = amount of heat energy gained or lost by substance = 1560 calories m = mass of sample in grams = 312g C = heat capacity (calorie/g oC) =? ΔT = change in temperature = 15 oC Solve for C C = q/mΔT = 1560cal/(312g)(15 oC) = 0.33cal/g oC
What is the specific heat of an unknown substance if 2000 J of energy are required to raise the temperature of 4 grams of the substance 5 degrees Celsius?
q = m x C x Δt, where q is amt of heat gained or lost, C is specific heat capacity, and Δt is change in temperature.Known:q = 2000Jm = 4gΔt = 5oCEquation:C = q/mΔtSolution:C = 2000J/4g5oC = 2000J/20goC = 100J/goC
If it takes 18.6 calories of heat to raise the temperature of 12.0 g of a substance by 10.0 degrees Celsius what is the specific heat of the substance?
Q = m*c*\delta t\, where Q = heat flow, m = mass, c = specific heat capacity, and \delta t\ = change in temperature. 88.2Cal = 13.4g*c*153 degrees C. Simple algebra yields c = 0.043 Cal*m^-1*K^-1.

Q equals m plus x t plus c In this equation what does Q t and c represent?
In the equation Q equals m plus x t plus c, Q represents the total quantity or value being measured or calculated. t represents the variable or time period being observed or measured. c represents the constant term or the y-intercept, which is the value of Q when t equals zero.

What is the equation for thermal energy?
== Q== mc(delta)T == Q=thermal energy m= mass c=specific heat (ex. water is 4.184 J/goc) deltaT= change in temperature
How the heat losses through insulation can be calculated?
Q = mct where q is the energy, m is the mass in kilograms, c is the specific heat in kelvins, and t is the change in temperature
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
How can you find specific heat value at 600 C for a compound?
You have to know mass in grams, energy (q) gained or lost in Joules, and change in temperature,ΔT, in degrees C. ΔT = Final temp - initial temp. The specific heat = q/(m)(ΔT) = J/g•oC
When was M. T. C. Cronin born?
M. T. C. Cronin was born in 1963.
What is the calculation for specific heat?
Q=cm(delta)T "Q" is the heat "C" is the specific heat "m" is the mass "(delta)T" is the change in temperature * just plug in what you have and then solve for what you don't have...and thats how you find the specific heat of a substance.
What is T M C?
T= Tragical M= MarvelousC= Cat
Which letter comes midway between M and T?
There are six letters between M and T. They are n, o, p, q, r, and s. The midway point is in the middle between P and Q, so there is no one letter midway between M and T. If you must have an answer, it would be both P and Q.
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.
