The answer is actually partially dependent on the starting temperature of the water (heat capacity is a function of temperature). You will still be close enough for most purposes if you assume that it takes 1 calorie to heat 1 gram of water 1 °C. With this assumption it takes 1000 calories to heat 1 kg of water °C and 5000 calories to heat 1 kg of water 5 °C. 5000 cal = 5 kilocalories = 20929 joules.
To determine the number of photons required to raise the temperature of 2.4g of water by 2.5K, you would need to know the energy of each photon, which depends on the wavelength/frequency of the light source. With this information, you can calculate the total energy needed to raise the temperature of the water by 2.5K and then convert this energy into the number of photons using the energy per photon value.
1 calorie is the energy required to raise 1 gram of water by 1 degree C. So it would take 5 calories to raise it by 5 degrees C.
To calculate the energy required to raise the temperature of water, you can use the formula: energy = mass x specific heat capacity x temperature change. The specific heat capacity of water is approximately 4.18 J/g°C. Plugging in the values, the energy required would be 10.0 g x 4.18 J/g°C x 25.0°C = 1045 Joules.
The specific heat capacity of water is 4.184 J/g°C. To calculate the energy required to raise the temperature of 150.0g of water by 44K, use the formula: energy = mass x specific heat capacity x change in temperature. Substituting the values, you get 150.0g x 4.184 J/g°C x 44 K = 27794.4 J, or 27.8 kJ of energy required.
Strictly speaking, yes. However, it's a fairly small effect. From 0 to 100 degrees Celsius, the constant pressure heat capacity of water in joules per gram kelvin is constant to two significant figures. You need to measure to at least three significant figures to see any variation, so for rough "back of the envelope" calculations, treating it as constant doesn't introduce a lot of error. And if the existing temperature is the boiling point or melting point of water, you can add lots of energy and get no increase in temperature as the energy goes into change of state, instead.
Depends on how high you want to raise the gram of water ;).
The energy required to raise the temperature of water can be calculated using the formula: Energy = mass * specific heat capacity * temperature change. Given the specific heat capacity of water is approximately 4.18 J/g°C, and m = ml, you can calculate the energy required by substituting the values into the formula.
To determine the number of photons required to raise the temperature of 2.4g of water by 2.5K, you would need to know the energy of each photon, which depends on the wavelength/frequency of the light source. With this information, you can calculate the total energy needed to raise the temperature of the water by 2.5K and then convert this energy into the number of photons using the energy per photon value.
The amount of energy required to raise the temperature of water by 1 degree Celsius is known as its specific heat capacity. For water, the specific heat capacity is 4.18 Joules/gram°C. This means that it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
Energy required to raise 1 gramme of water by 1 degree C = 1 calorie also, 1 calorie = 4.186 Joules
Kilowatts is a unit of energy rate, while the temperature required to raise a specific volume of water by a specific amount of degrees is a unit of energy, not energy rate. The question cannot, therefore, be answered as stated. Please restate the question.
The amount of energy required to raise the temperature of 1 kg of water by 1 degree Celsius is approximately 4,186 Joules. Therefore, to raise the temperature by 2 degrees Celsius, you would need about 8,372 Joules of energy.
The amount of energy required to raise the temperature of one gram of water by one Celsius degree is called the specific heat capacity of water. It is approximately 4.18 joules per gram per Celsius degree.
Specific heat capacity.
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
1 calorie is the energy required to raise 1 gram of water by 1 degree C. So it would take 5 calories to raise it by 5 degrees C.
No. The quantity of energy required to raise the temperature of water is different depending on the phase of water. This is especially true at or near a phase transition as thermal energy is absorbed during a phase transistion thus altering the amount of energy required to raise the temperature of said water.
