It is a calorie
The specific heat capacity of water is 4.186 J/g°C. Since there are 1000 grams in a kilogram, it would require 20,930 Joules of energy to increase the temperature of a kilogram of water by 5 degrees Celsius.
Kinetic energy = 0.5 x mass x velocity2 So you just need mass of the object and its velocity.
The large calorie, kilogram calorie, dietary calorie or food calorie approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
To calculate the energy needed to change ice at -32.9 degrees to water at 75 degrees, you need to consider the energy required for three steps: Heating ice from -32.9 degrees to 0 degrees (specific heat capacity of ice) Melting ice at 0 degrees into water at 0 degrees (latent heat of fusion of ice) Heating water from 0 degrees to 75 degrees (specific heat capacity of water) Once you have the energy needed for each step, you can add them together to find the total energy required.
In physics, a calorie is a unit of energy measurement. It is defined as the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. This measurement is used to quantify the energy content of food and the energy expended during physical activities.
The definition of a calorie is that, it's the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
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.
The amount of heat required to melt one kilogram of a substance is known as the heat of fusion or the latent heat of fusion. It represents the energy needed to change a solid into a liquid at its melting point without a change in temperature.
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.
2.6 kcal refers to a measurement of energy, specifically kilocalories, which is commonly used in nutrition to quantify the energy content of food. One kilocalorie is the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius. In dietary terms, this value indicates how much energy your body can obtain from consuming a particular food item. Thus, 2.6 kcal represents a relatively small amount of energy, typically found in low-calorie foods or specific portions.
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C).
