How much heat is needed to raise 8 kg of water from 4 degress celsius to 83 degrees celsius?
The amount of heat needed to raise the temperature of a substance can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity of water (4.18 J/g°C), and ΔT is the temperature change. Plugging in the values, we get Q = 8 kg * 4186 J/kg°C * (83°C - 4°C) = 2,309,056 Joules. Therefore, 2,309,056 Joules of heat energy is needed to raise 8 kg of water from 4°C to 83°C.
Is burnt wood a chemical change?
it is a chemical changeYes. Wood is composed of a number of complex chemical compounds, and cellulose is a principle one. Much of the material in wood is reduced to carbon dioxide and water, but there are a considerable number of combustion byproducts and also many products of incomplete combustion. But through burning, wood undergoes a chemical change to become ash and all the stuff that is carried away in the smoke stream. Heat, of course, is a byproduct. when the ashes are formed they can not be formed into a log or peice of woodYes, burning wood is a chemical change. - A.GibbsYes; the fire (combustion) is using oxygen in the air to release heat energy and carbon atoms in the wood. Wood is mostly made up of a gas called cellulose and the burning allows oxygen molecules to mix with the cellulose. This exerts various gases and the heating will obviously convert the wood to ash and scoot.its chemical changeYes, wood undergoes a chemical change when it is burned. For the most part it is a redox reaction.Yes
Specific heat capacity of aluminum in J kgC?
Most materials, including aluminum, have a thermal conductivity that can vary with temperature. Most measurements are made at specified temperatures. Some use room temperature, about 25 degrees C. The conductivity is easy to find in engineering handbooks or the Web. But is measured in watts/degree K/m. 250 in the case of aluminum.
How much energy must be added to a 1 kg piece of glass with a specific heat of 644 J kgC to increase its temperature from 20 C to 100 C?
The energy required to increase the temperature of a substance can be calculated using the formula: Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values gives Q = 1kg * 644 J kgC * (100C - 20C) = 51,520 J. Therefore, 51,520 Joules of energy must be added to raise the temperature of the glass.
When was Anyang KGC created?
Anyang KGC was created in 1997.
How much heat does it take to raise the temperature of 7.0 kg of water from 25C to 46C The specific heat of water is 4.18 kJ(kgC).?
To calculate the heat required to raise the temperature of water, you can use the formula: Q = m * c * ΔT, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Plugging in the values, we get Q = 7.0 kg * 4.18 kJ/(kg°C) * (46°C - 25°C). Calculate this to find the heat energy required.
What is the specific heat of dry air and how does it affect the temperature changes in a system?
The specific heat of dry air is approximately 1.005 kJ/kgC. This means that it takes 1.005 kilojoules of energy to raise the temperature of 1 kilogram of dry air by 1 degree Celsius. The specific heat of dry air affects temperature changes in a system by determining how much energy is needed to raise or lower the temperature of the air. Higher specific heat means it takes more energy to change the temperature, while lower specific heat means it takes less energy.
