How many joules of heat required to raise the temperature of 25 grams of h2o from 21 degrees Celsius to 35.5 degrees?
The specific heat capacity of water is 4.184 J/g°C. The change in temperature is 35.5°C - 21°C = 14.5°C. Using the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature, you can calculate that the heat required is approximately 1554.7 joules.
How many calories are required to increase the temperature of a 27.3 g sample of copper from 36.2 degrees Celsius to 74.4 degrees Celsius?
I will work in Joules, then convert to calories.q(Joules) = mass * specific heat * change in temperature Cq = (27.3 g Cu)(0.385 J/gC)(74.4o C - 36.2o C)= 402 Joules (1 calorie/4.184 Joules)= 96.1 calories===========
A particular sample of iron requires 562 Joules to raise its temperature from 25 degreee Celsius to 50 degrees Celsius. What must be the mass of the sample of iron?
The change in temperature is 25 degrees Celsius, meaning it takes 22.48 joules per degree of change. The specific heat of iron is 0.449 J/g degree Celsius. This means that the mass of iron must be 50.07 grams
What is true about waters specific heat?
Water has a high specific heat capacity, which means it can absorb and release a large amount of heat without much change in temperature. This property allows water to help regulate Earth's climate by absorbing heat in the summer and releasing it in the winter.
What is the bomb calorimeter formula used to calculate the heat released during a chemical reaction?
The bomb calorimeter formula used to calculate the heat released during a chemical reaction is: q C x T where: q heat released (in joules) C calorimeter constant (in joules per degree Celsius) T change in temperature (in degrees Celsius)
How many joules are needed to change the temperature of 100 g of water from 20 degrees Celsius to 40 degrees celsius?
8.200 J
How many joules are absorbed by the water with a mass of 8 kg in order to raise the temperature from 20 degrees to 70 degrees?
q(joules) = mass * specific heat * change in temperature ( 8 kg = 8000 grams ) q = (8000 grams H2O)(4.180 J/gC)(70o C - 20o C) = 1.7 X 106 joules ============
How many joules equal one degree Fahrenheit?
One degree Fahrenheit is equal to 0.5556 degrees Celsius. To convert this temperature change to energy in joules, you would need to know the specific heat capacity of the substance in question. The formula to calculate the energy change in joules is Q = mcΔT, where Q is the energy change, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change in degrees Celsius.
What is the quantity of heat in joules needed to raise the temperature of 40.0g of Al from 25 degrees Celsius to 50 degrees Celsius?
E = mass x specific heat x Δ°T Δ°T = new temperature - original temperature where Δ°T is equal to temperature change (Celsius in this case). The specific heat of Al is 0.900 J/g°C. Before we proceed to find the quantity of heat in joules, we must first find the temperature change. To calculate the temperature change, we must subtract the original temperature from the new temperature. Δ°T = 50°C - 25°C = 25°C In order to find the quantity of heat (joules), we must multiply mass, specific heat, and the temperature change (calculated above). E = 40.0g x 0.900 J/g°C x 25°C = 900 Joules or 9.0 x 102 Joules
How many joules are needed to change the temperature of 1 gram of water by 1C?
It takes 4.184 joules of energy to change the temperature of 1 gram of water by 1 degree Celsius.
Is heat energy measured in units of joules degrees Celsius and in degrees Fahrenheit?
Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.
How much heat in joules to heat a 40 g sample of aluminum from 73 degrees f to 142 degrees f?
q( in Joules ) = mass * specific heat * change in temperature [ convert temps--Tf = Tc(1.80) + 32 ] q = (40 g)(0.90 J/gC)(61.1o C - 22.8o C) = 1.4 X 103 Joules =============
How many joules of heat required to raise the temperature of 25 grams of h2o from 21 degrees Celsius to 35.5 degrees?
The specific heat capacity of water is 4.184 J/g°C. The change in temperature is 35.5°C - 21°C = 14.5°C. Using the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature, you can calculate that the heat required is approximately 1554.7 joules.
How many joules of energy are required to raise the temperature of 74g of water from 20 degrees to 70 degrees celsius?
The specific heat capacity of water is 4.184 J/g°C. The change in temperature is 70°C - 20°C = 50°C. Using the formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change, we get Q = 74g * 4.184 J/g°C * 50°C = 15,535.2 Joules.
What is the total heat loss if you have 18 grams of aluminum and the temperature changes from 64 degrees Celsius to 48 degrees Celsius?

How many grams of water could be heated from 25 degrees Celsius to 100 degrees Celsius upon absorption of 4.22 kcal of heat?
E = mass x specific heat x Δ°t (temperature change)------------------ Energyspecific heat * temperature change = massΔ°t = new temperature - original temperatureIn order to calculate the mass of water able to be heated, we must divide the given energy by the result of specific heat times temperature change. Before proceeding to do such, we must calculate the temperature change, as well as convert cal to joules. It is also important to know that water's specific heat is 4.184 J/g°C.1. Calculate temperature change.Δ°t = 100°C-25°CΔ°t= 75°C2. Convert kcal to joules (multiply kcal * 103 * 4.184 joules [J]). (kcal --> joules)Joules = 4.22 kcal x 103 cal x 4.184 J/g°C = 17656.48 Joules------------------------ 1 kcal ------ 1 cal3. Find mass.Mass = 17656.48J(4.184J/g°C * 75°C) = 56.3g
