Why is a great deal of heat needed to raise the temperature of water by a given amount?
Water has a high specific heat capacity, meaning it can absorb a lot of heat energy before its temperature increases significantly. This is because the molecular structure of water allows for hydrogen bonding, which requires energy to break. As a result, a large amount of heat is needed to raise the temperature of water by a given amount.
Is the amount of energy that food contains measured in calories?
Yes, the amount of energy that food contains is measured in calories. When we refer to calories in the context of food, we are actually referring to kilocalories (kcal), which represent the amount of energy needed to raise the temperature of 1 kilogram of water by 1 degree Celsius.
A blank is a measure of energy in food?
The calorie (usually expressed in kilocalories)
How much energy is needed to raise the temperature of air by 1 degree Celsius?
The amount of energy required to raise the temperature of air by 1 degree Celsius depends on various factors such as the volume of air and its specific heat capacity. As a rough estimate, it takes about 1.005 kJ of energy to raise the temperature of 1 cubic meter of air by 1 degree Celsius.
What is an amount of energy needed to raise kg of a subsyance1c?
The amount of energy needed to raise the temperature of a substance is calculated using the formula ( Q = mc\Delta T ), where ( Q ) is the heat energy (in joules), ( m ) is the mass of the substance (in kilograms), ( c ) is the specific heat capacity (in joules per kilogram per degree Celsius), and ( \Delta T ) is the change in temperature (in degrees Celsius). This formula helps determine how much energy is required to achieve a desired temperature increase for a given mass of a substance.
A calorie is the amount of energy needed to?
raise the temperature of the body by 1 Celsius
What is the amount of energy needed to raise the temperature of 1 gram of water 1 degree celsius?
The amount of heat necessary to raise 1 gram of a substance by 1 degree Celsius is known as?
What most influences the amount of energy needed to change the temperature of a substance?
The amount of energy needed to change the temperature of a substance is most influenced by its specific heat capacity, which is the amount of energy required to raise the temperature of a given mass of the substance by 1 degree Celsius. Substances with higher specific heat capacities require more energy to change temperature compared to those with lower specific heat capacities. Additionally, the mass of the substance being heated also plays a role in determining the amount of energy needed.
What is the amount of energy needed to raise 1 kg of a substance 1 degrees Celsius?
The amount of energy needed to raise the temperature of 1 kg of a substance by 1 degree Celsius is called the specific heat capacity of the substance. Specific heat capacity is usually measured in joules per kilogram per degree Celsius (J/kg°C). Different substances have different specific heat capacities.
What is the amount of energy needed to raise the temperature of 1kg of water by 1 degree Celsius?
phase change
What is a calorine?
A calorine is the amount of energy needed to raise the temperature of 1gram of water 1 degree celsius.
A difference in this results in different ending temperatures when the same amount of thermal energy is added to two different substances?
The specific heat capacity of a substance determines how much thermal energy is needed to raise its temperature. Therefore, substances with different specific heat capacities will reach different ending temperatures when the same amount of thermal energy is added. Substances with higher specific heat capacities will have smaller temperature increases compared to substances with lower specific heat capacities.
What are the factors that determine the amount of energy needed to raise the temperature?
The amount of energy needed to raise the temperature of a substance depends on its mass, specific heat capacity, and the desired temperature increase. The formula to calculate this is: Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change.
What is a simple definition of specific heat?
the amount of heat needed to raise the temeperature of 1kg of some material by 1 degrees celsius(or 1K)
What is the amount of energy needed to change the temp of a substance called?
The amount of energy needed to change the temperature of a substance is known as heat. It is measured in units such as calories or joules. It takes a specific amount of heat energy to raise the temperature of a substance by a certain number of degrees Celsius.
Which of these substances requires the least amount of energy to raise its temperature 'wood' 'water' 'gold' or 'aluminum'?
Aluminum requires the least amount of energy to raise its temperature compared to wood, water, and gold. This is because aluminum has a lower specific heat capacity, meaning it can heat up more quickly with less energy input.
Define Joule calorie and Kcal?
A calorie is the amount of energy that needed to raise the temperature of one gram of water one degree Celsius. The Joule is the SI unit for energy.
