How many grams of water when supplied with 348J of heat will gain a temperature of 5.2C?
To find the grams of water, we first need to calculate the change in temperature of the water using the specific heat capacity of water (4.18 J/g°C). Delta T = Q / (m * C), where Q is the heat supplied (348 J), C is the specific heat capacity of water (4.18 J/g°C), and m is the mass of water in grams. Rearranging the formula to solve for mass, we get m = Q / (C * delta T). Plugging in the values, we find m = 348 / (4.18 * 5.2) ≈ 16.7 grams of water.
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?
Using the formula q = mcΔT, where q is the heat absorbed, m is the mass, c is the specific heat, and ΔT is the change in temperature, we can calculate the specific heat of the metal. Plugging in the given values, we have 124.2 J = (18.0 g) * c * (40°C - 25°C). Solving for c gives us a specific heat of approximately 0.46 J/g°C for the unknown metal.
How much heat in kilojoules is released when 25.0 g of water is cooled from 85.0ºC to 40.0ºC The specific heat of water is 4.184 J(gC).?
The heat released can be calculated using the formula: Q = m * c * ΔT, where Q is the heat released, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Converting the units, the heat released is approximately 2.44 kJ.
If a 4.0 g sample of glass was heated from 274 k to 314 and was foundd to absorb 32 j of energy as heat calculate the specific heat of this glass?
The specific heat capacity of glass can be calculated using the formula q = m * C * ∆T, where q is the heat absorbed (32 J), m is the mass (4.0 g), C is the specific heat capacity, and ∆T is the change in temperature (40 K). Rearranging the formula to solve for C gives C = q / (m * ∆T), which equals 0.2 J/gK for the specific heat capacity of this glass.
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?
The specific heat can be calculated using the formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat, and ΔT is the temperature change. Plugging in the values, we get 2000 J = 4g * c * 5°C. Solving for c gives a specific heat of 100 J/g°C.
What is the correction equation Q m x c x T rearranged to solve for specific heat?
The specific heat (c) can be calculated by rearranging the equation as c = Q / (m x T), where Q is the heat energy transferred, m is the mass of the substance, and T is the temperature change.

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
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.
