What else can I help you with?
How many kWh's does it take to heat water from 0 degrees C to 37 degrees C with proof please?
To raise the temperature of one cc of water requires i calorie of heat . you did not specify the volume.
Specific heat of air?
The specific heat of air at 0 degrees Celsius is 1.01 Joules per gram or J/g. The specific heat of a substance is defined as the quantity of heat per unit mass needed to raise its temperature by one degree Celsius.
What variable represents specific heat in the equation?
In the equation for calculating heat transfer, the variable that represents specific heat is usually denoted by ( c ). Specific heat is defined as the amount of heat required to raise the temperature of one unit mass of a substance by one degree Celsius (or one Kelvin). The equation is often expressed as ( Q = mc\Delta T ), where ( Q ) is the heat added, ( m ) is the mass, and ( \Delta T ) is the change in temperature.
How many calories are required to raise the temperature of 105 grams of water from 30.0 degrees C to 70.0 degrees C?
q (amt of heat) = mass * specific heat * temp. differenceThe specific heat of water is 1.00 cal/goC & the temperature difference is 70-30 = 40oCq = (105 grams)*(1.00 cal/goC)*(40oC)= 4,200 calories
200.0 Joules of heat is required to raise the temperature of an object sample by 3.00C If the specific heat of the object is 01490 JgC what is the mass of the sample in kilograms?
Use the equation for specific heat: energy = mass x (temperature difference) x (specific heat). Replace the numbers you know, and solve for mass. Since it seems that the specific heat is specified per gram, you'll initially get the mass per gram. Converting that to kilograms is quite easy.
Does metal with high heat capacity raise temperature of water more than a metal with low heat capacity?
No, metal with high heat capacity will not necessarily raise the temperature of water more than a metal with low heat capacity. Heat capacity is a measure of the amount of heat energy required to raise the temperature of a substance by a certain amount, so a metal with higher heat capacity can hold more heat energy but may not necessarily transfer it more efficiently to the water. The efficiency of heat transfer depends on factors like conductivity and surface area of the metal.
Where did heat energy used to melt metal ores come from?
Heat energy used to melt metal ores typically comes from burning fuels such as coal, oil, or natural gas in a process called smelting. The fuel provides the necessary heat to raise the temperature of the ore to its melting point, allowing the metal to be extracted from the ore.
What is the specific heat of a substance?
The amount of heat a substance can hold.
What is the best definiton for specific heat?
The specific heat is the necessary energy to raise the temperature of a mass unit (gram, kilogram, mole) of a substance with one kelvin.
How many joules of heat are necessary to raise temperature of 125g of copper from 25 degrees celsius to 300degrees celsius?
The answer is 53,683 kJ.
What does the amount of heat needed to raise an objects temperature depend on?
The amount of heat needed to raise an object's temperature depends on its mass, its specific heat capacity, and the temperature change desired. Objects with higher mass require more heat to raise their temperature, while those with higher specific heat capacities absorb more heat for the same temperature change.
Taking heat out of the air will do what to the temperature?
Removing heat from the air will lower its temperature.
What metal will have the highest temperature with specific heat of aluminum 0.215 copper 0.092 and silver of 0.057?
I would like to start off by saying that: Energy absorbed by metal = mass of metal x specific heat capacity of metal x change in temperature of the metal If the same amount of energy is given to all three metals, there would be the highest temperature increase in the metal with the lowest specific heat capacity. Therefore, Silver would be the answer.
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.
If a substance has a specific heat less than one would it take more or less heat to raise the temperature?
If a substance has a specific heat less than one, it would take less heat to raise its temperature compared to a substance with a specific heat of one. This is because substances with lower specific heat values require less energy to raise their temperature by a certain amount.
How much heat is required to raise the temperature of the room?
The amount of heat required to raise the temperature of a room depends on the room's size, insulation, current temperature, and the desired temperature. It can be calculated using the specific heat capacity of air, room volume, and the temperature difference.
If the same amount of heat is added to 25.0 g samples of each of the metals in the chart which metal will experience the largest temperature change (AKS 7E - DOK 2)?
The metal with the lowest specific heat capacity will experience the largest temperature change when the same amount of heat is added. This is because metals with lower specific heat capacities require less heat to raise their temperature compared to metals with higher specific heat capacities. Therefore, you should select the metal with the lowest specific heat capacity from the chart to determine which one will experience the largest temperature change.
