What is used to find the specific heat capacity of a substance?
The equation for specific heat is: C = q/temp. change x mass. C is a substance's specific heat, which is a constant for every substance. q is its heat capacity in joules, temp. change is the change in temperature in degrees Celsius, and mass is in grams.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.
How many miligrams in a kilogram?
there are 1,000,000 milligrams in a kilogram
Is kilo short for kilogram?
Yes kilo is short for the word Kilogram . :)
What metal is the heating element in a kettle?
It's basically the same as the glow wires in a toaster, or the filament in an incandescent light bulb. When a current is passed through the element, the resistance makes the element heat up.Another AnswerWhen an electric current passes through the heating element, it does work on the heating element, water, and the kettle itself. This causes the internal energy of the element, water, and kettle to rise, and this is accompanied by an increase in temperature. When the temperature exceeds that of the surroundings, some energy is lost to the surroundings through heat transfer. The equation that describes this is:W - Q = [m c (T2 - T1)]water +[m c (T2 - T1)]kettleWhere:W = work done (joules)Q = heat transfer (joules)m = mass (kilograms)c = specific heat capacity (joules per kilogram kelvin)T2 = final temperature (kelvin)T1 = initial temperature (kelvin)
How much energy is needed to increase the temperature of a kilogram of water 5 degrees?
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.
What amount of heat needed to increase the temperature of a 1-kilogram substance by 1 and degC is known as the?
The amount of heat needed to increase the temperature of a 1-kilogram substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is a measure of how much heat energy is required to raise the temperature of a given mass of the substance by one degree Celsius.
What does it mean to say that a material has a high or low capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
The amount of heat needed to increase the temperature of one kilogram of substance by 1 and degc?
The amount of heat needed to increase the temperature of one kilogram of a substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is measured in joules per kilogram per degree Celsius (J/kg°C). Different substances have different specific heat capacities due to their molecular structure and composition.
Why does it take longer for a kilogram of water than a kilogram of copper to reach the same temperature?
The reason it takes longer for a kilogram of water than a kilogram of copper to reach the same temperature is because of the specific heat capacity of each. This is the amount of energy (heat) it takes to raise the temperature of one kilogram of material by 1 degree Kelvin or Celsius.
How much energy is needed to increase the temperature of 1kg of water by 10c?
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).
What does it mean to say that the specific heat capacity of water is greater than that of iron?
Heat capacity is the amount of heat needed to increase the temperature of an element (a given mass) by a temperature unit.Specific Heat Capacity is the amount of heat in Joulesneeded to heat 1kg of an element by 1 degree Kelvin.Joules per Kilogram KelvinIf the SHC of water is higher than that of iron, it means, you need more heat to increase the temperature of 1kg of water in 1 degree Celsius, than the heat you need to increase the temperature in 1 degree Celsius of the same mass of iron.P.S.A Celsius temperature difference is the same as a Kelvin temperature difference. In measuring SHC, we only need to focus on temperature difference rather than the temperature value. Add 273.15 to the Celsius measurement of the temperature to get the Kelvin temperature value.
What is the amount of heat needed to raise that temperature of 1 kilogram of water 1 degree 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.
How much energy must be added to a 2 kilogram piece of it to increase its temperature from 20c to 30c?
The amount of energy required to increase the temperature of a substance can be calculated using the equation Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Assuming a specific heat capacity of water (4.18 J/g°C), the energy required would be approximately 1676 Joules.
What heats more quickly a kilogram of water or a kilogram of copper?
A kilogram of copper heats more quickly than a kilogram of water because copper has a lower specific heat capacity than water. This means it takes less energy to raise the temperature of copper compared to water.
Is one pint a kilogram?
No, a pint is measure of volume or capacity. A kilogram is measure of weight.
What is the metric unit of mass and capacity?
Mass . . . kilogram Capacity . . . cubic meter
