Which measures a bigger heat change 1c or 1f?
1C in 1.8 times as large a change.
How much heat is required to change 0.2kg of ice at -5 degrees to water at 5 degrees?
Heat required for this transition is given as the the sum of three heatsheat required for heating the ice from -5 degree Celsius +latent heat(conversion of ice at zero degree to water at zero degrees)+heat required to heat the water from 0 to 5 degree CelsiusHeating of ice=m x s x delta T,where m is the mass ,s is the specific heat of ice=200x0.5x5=500calmelting of ice=mxlatent heat=200x80=16,000calHeating of water=m x s x delta T,where m is the mass ,s is the specific heat of water =200x1x5=1000calTotal heat required=500+16,000+1000=17,500 cal
What is the specific heat of air in imperial units?
Specific heat of air is 0.24 BTU/lb/degree F
How many Btu are required to change 600 pounds of water at 75 degrees F to steam at 212 degrees F?
1 BTU is required to raise 1lb of water 1 degree F in 1 hour. 212-75=137 degrees 600 lbs water x 137 degrees= 82,200 BTU's required to change 75 degree water to 212 degree water. To change 212 degree water to 212 degree steam it requires 970 btu's (latent heat of vaporization) per lb of water 970 btu x 600 lbs water = 582,000 btu Answer - 582,000 btu+ 82,200 btu = 664,200 btu's
How many kw are needed to heat 1 liter of water 1 degree?
1 litre for 1 degree in 1hour is 1,16 kW/h
Which measures a bigger heat change 1c or 1f?
1C in 1.8 times as large a change.
Which measures a bigger heat change 1 degrees Fahrenheit or 1 degrees celsius?
One degree Celsius is equivalent to a larger amount of heat change than one degree Fahrenheit. This is because the Celsius scale is based on a larger temperature interval between freezing and boiling points of water (0°C to 100°C) compared to the Fahrenheit scale (32°F to 212°F).
What term describes how much energy it takes to change the the temperature of a substance?
specific heat capacity
What is the relation between heat and temperature?
The difference between heat and temperature is that heat is the amount of energy given off by a piece of matter, and Specific Heat indicates the amount of heat necessary to change 1g of something by 1 degree. Temperature measures change in heat.
What is the quantity of heat required to change an objects temperature to exactly 1 degree Celsius?
The quantity of heat required to change an object's temperature by 1 degree Celsius depends on its specific heat capacity and mass. The formula to calculate this is Q = mcΔT, where Q is the heat energy, m is the mass of the object, c is the specific heat capacity, and ΔT is the change in temperature.
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.
Is a calorie a measure of mechanical energy?
No, it measures the ammount of heat output that would heat a millilitre of water 1 degree Celsius. So if you were to burn 1000 calories of energy, it would heat one millilitre 1000 degrees Celsius or it would heat 1 litre 1 degree Celsius.
What instrument that measures how much heat energy is stored in a substance is called a?
A calorimeter is an instrument that measures the amount of heat energy stored in a substance by determining the temperature change during a chemical reaction or physical process.
What is the relationship of mass of an object to the amount of heat required to change its temperature?
The bigger he mass the more heatt required to change its temp.erature; Heat=m(T2-T1)
What is heat fusion and heat of vaporization measures of?
Heat fusion is the amount of heat energy required to change a solid substance into a liquid at its melting point, while heat of vaporization is the amount of heat energy required to change a liquid substance into a gas at its boiling point. Both measures are properties of the substance and represent the energy needed to break intermolecular forces to change between phases.
Why is more heat needed to vaporize water than gasoline?
Gasoline has a less boiling point (72 degree Celsius) While water has a bigger boiling point (100 degree Celsius)
What is the relationshio between specific heat and temperature?
Specific heat is a measure of the amount of heat required to raise the temperature of a substance by one degree Celsius. It is an intrinsic property of the material. As temperature increases, the specific heat of a substance typically remains relatively constant unless undergoing a phase change.
