How many calories will it take to raise the temperature of a 36 g gold chain from 20 and degC to 125 and degC?
To calculate the energy required to raise the temperature, you can use the formula: energy = mass x specific heat capacity x temperature change. The specific heat capacity of gold is 0.129 J/g°C. Plugging in the values for mass, specific heat capacity, and temperature change, the energy required would be approximately 364.86 Joules. To convert Joules to calories, divide by 4.184 to get approximately 87.2 calories needed to raise the temperature of the gold chain.
What amount of heat needed to increase the temperature of a 1-kilogram substance by 1 and degC is known as the?
The amount of heat needed to increase the temperature of a 1-kilogram substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is a measure of how much heat energy is required to raise the temperature of a given mass of the substance by one degree Celsius.
The specific heat of a certain type of cooking oil is 1.75 cal(g and middot and degC). How much heat energy is needed to raise the temperature of 2.40 kg of this oil from 23 and degC to 191 and degC?
The change in temperature is ΔT = 191°C - 23°C = 168°C. The heat energy Q required is given by the formula Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the temperature change. Plugging in the values: Q = 2.4 kg * 1.75 cal/(g°C) * 168°C = 7056 cal = 7.056 kcal.
What is the temperature -273 and degC?
-273 degrees Celsius is equivalent to 0 Kelvin. This is known as absolute zero, the lowest possible temperature where all molecular motion stops.
The amount of heat needed to increase the temperature of one kilogram of substance by 1 and degc?
The amount of heat needed to increase the temperature of one kilogram of a substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is measured in joules per kilogram per degree Celsius (J/kg°C). Different substances have different specific heat capacities due to their molecular structure and composition.

When A balloon has a volume of 10500 liters and the temperature is 15 and degC. If the temperature were -25 and degC what would the volume of the balloon be?
It would be approx 9042 litres.
How much heat is necessary to change 565 g of ice at -13 and degC to water at 20 and degC?
To calculate the heat needed to change ice to water, we use the specific heat capacities and latent heat of fusion. First, calculate the heat needed to raise the temperature of 565 g of ice from -13°C to 0°C using specific heat capacity of ice. Then, calculate the heat needed to melt the ice at 0°C to water at 0°C using the latent heat of fusion for ice. Finally, calculate the heat needed to raise the temperature of water from 0°C to 20°C using the specific heat capacity of water. Add these three values together to find the total heat required.
How much heat in joules would you need to raise the temperature of 1kg of water by 5 and degC?
You would need 20,920 Joules of heat to raise the temperature of 1kg of water by 5°C. This value is calculated using the specific heat capacity of water, which is 4186 J/kg°C.
What would happen to a sample of water at 30 and degC if it is heated until the temperature reaches 120 and degC?
Water is transformed in vapors.
The specific heat of gold is 0.031 caloriesgram and degC. If 10.0 grams of gold were heated and the temperature of the sample changed by 20.0 and degC how many calories of heat energy were absorbed by?
The needed heat is:Q = 10 x 20 x 0,031 = 6,2 calories
A solid substance with a mass of 200 grams is at its melting point temperature in a calorimeter While the substance changes from a solid to a liquid at the same temperature the 400-gram mass of water?
The heat required for the substance to melt at its melting point is given by the formula: ( q = n \cdot \Delta H_f ), where ( q ) is the heat absorbed, ( n ) is the number of moles, and ( \Delta H_f ) is the heat of fusion. The heat released by the water during the process is: ( q = m \cdot c \cdot \Delta T ), where ( m ) is the mass, ( c ) is the specific heat capacity of water, and ( \Delta T ) is the temperature change. By equating these two equations, one can solve for the heat of fusion.
How much did the temperature rise if it was -6 and At midday the temperature is 9 and degC. By how much did the temperature rise?
40
) The temperature of a sample of water changes from 10 and degC to 20 and degC when the water absorbs 100 calories of heat. What is the mass of the sample?
one calorie of heat is able to raise one gram of water one degree Celsius so 400 calories could raise 1g of water 400 degrees, so it would raise the 80g by(400/80) 5 degrees Celsius plus the initial temp of 10 degrees, the 80g of water would have a final temp of 15 degrees Celsius
What sized of copper cable to replaced 240 square millimeter aluminium cable?
Copper is a better conductor by weight, but aluminum is better by weight, so the copper will be thinner but heavier. You will see that a 250 kcmil aluminium wire will get you 170 amps at 60 degC while a 000 (or 3/0) copper wire will get you 165 amps at 60 degC. I think you mean circular mils, not square millimeters.
