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.

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.
How much heat is needed to raise the temperature of 6.00 g of copper by 15.0 and degC?
The specific heat capacity of copper is 0.385 J/g°C. Using the formula Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the temperature change, you can calculate that 34.65 J of heat is needed to raise the temperature of 6.00 g of copper by 15.0°C.
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.
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.
If a liquid sample of naphthalene is heated and remains at 218 and degC until it is completely vaporized you know that 218 and degC is the of naphthalene.?

) 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
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
