The formula for the quantity of heat Q = m s t
m- mass 0.375 kg s - specific heat capacity of water (4180 J/kg/K) t - the temperature change (25 deg C)
So, Q = 0.375 x 4180 x 25 = 39187.5 J
The heat needed can be calculated using the formula: Q = mc∆T, where Q is the heat, m is the mass of water, c is the specific heat capacity of water (4186 J/kg°C), and ∆T is the change in temperature. Plug in the values to find the heat needed.
This calculation is used to find the specific heat capacity of a substance. The specific heat capacity is a measure of how much energy is needed to raise the temperature of a given amount of a substance by 1 degree Celsius. The formula used is: specific heat capacity = energy (in Joules) / (mass (in grams) * change in temperature (in Celsius)).
To calculate the mass of NaCl needed to raise the boiling point of 1.000 kg of water by 2.00 degrees Celsius, you would use the equation: ΔTb = i * Kf * m, where i is the van't Hoff factor (for NaCl, it is 2), Kf is the cryoscopic constant for water (1.86 °C kg/mol), ΔTb is the boiling point elevation (2.00 °C), and m is the molality of the solution (in mol/kg). Solve for 'm' first and then use that value to calculate the mass of NaCl needed.
The amount of energy required to raise 1 kg of a substance by 1 degree Celsius is called the "Specific Heat Capacity," or just specific heat, of a substance. This is an intensive property of the particular substance.
To lower pH, you can add pH decreaser (such as sodium bisulfate) following manufacturer's instructions. To raise chlorine levels, you can add liquid chlorine or chlorine tablets according to the pool size and current chlorine levels. Retest after a few hours and adjust as needed.
that means more energy is needed to raise the temperature of 1kg of liquid from 1 Celsius than water.
Q=mcΔT Q=14 x 4200 x 21.6 Q=1270080J
The amount of heat necessary to raise 1 gram of a substance by 1 degree Celsius is known as?
Yes, one calorie is the amount of heat needed to raise the temperature of 1 kilogram of water 1 degree Celsius.
raise the temperature of the body by 1 Celsius
The relevant equation behind this problem is Q=m*c* ΔT Where Q is the energy that must be added to or taken from the system, m is the mass of the object, c is the objects specific heat, and ΔT is the change in temperature in Celsius or Kelvin. Plugging in the given values we get that Q=.015kg * 128J/(kg*C) * 10C=19.2J. Therefore, you need 19.2 joules of heat in order to raise the temperature of a .015kg sample of lead by 10 degrees Celsius.
The amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius is 4186 Joules, which is the specific heat capacity of water.

A calorine is the amount of energy needed to raise the temperature of 1gram of water 1 degree celsius.
The amount of energy needed to raise the temperature of 1 kg of a substance by 1 degree Celsius is known as the specific heat capacity of the substance. It varies depending on the substance and is typically measured in joules per kilogram per degree Celsius (J/kg°C).
