What is the measure of kinetic energy of a substances molecules?
temperature is the measure of the average kinetic energy of a substances molecules, though energy is in joules and temperature is in Kelvin.
How do scientists determine how many calories a food has?
They breakdown the food to its simplest form then place it in a metal cup which is in a water box. After they place the cup in the water they take the temperature of the water (Tinitial). When they have the temperature of the water they ignite the food and check the temperature after the fire(Tfinal). Then they use the equationq=Masswater x specific heatwaterx ΔTwater(q=Heat in calories or joules) (T=temperature) (ΔTwater=Tfinal-Tinitial) (spefic heat of water= 4.18 J/g °C) (Masswater= Mass of water in box - mass of box w/o water)(joules to calore conversion 1 calorie=4.184 Joules)
How do units that are used to measure heat are different from the units that are used to measure temperature?
Heat is measured in calories or BTU, whilst temperature is measured in degrees Celsius or Fahrenheit.1 calorie is the heat to raise 1 gram of water by 1 degree C1 BTU is the heat to raise 1 pound of water by 1 degree FHeat is the amount of energy in a system measured in Joules. Temp is the MEASURE of the AVERAGE molecular motions in a system F/CAnother AnswerIn SI, heat is measured in joules and temperature in kelvin.
How much heat energy is required to raise the temperature of 15 g of water 25 degrees Celsius?
6480 calories8LBs X 15 gallons x 54 DEGREES = 6480 CALORIES
How many joules of energy are released when 45.0 g of water cools from 18.0 oC to 7.0 oC?
energy = mass x specific heat x temperature change = 45 x 4.181 x 11 J = 2069.595 J
What is the amount of thermal energy that must be added to change ice at the melting point completely into water?
About 333 joules / gram.
What is basic difference between melting and fusion?
Melting point is the temperature at which something melts. Like ice has a melting point of 0 Celsius. The heat of fusion is the heat energy that is absorbed (or released) when a substance melts (or freezes) an is measured in energy units, either calories or joules. Ex. One gram of ice must absorb 80 calories of heat energy to change into liquid water.
How much is a energy in joules?
Unit of energy; approximately 4.2 joules
What is the number of joules in 22000 british thermal units?
1 BTU = 1 055.05585 joules so 22000 BTU = 23211228.75764 joules (approximately)
What are the units used is temperature?
calories and joules
How many calories in 420 Joules?
Approximately 100 calories.
How do you convert Joules To fahrenheit?
You cannot convert Joules to Fahrenheit. They are two different kinds of measurements. Fahrenheit measures temperature and Joules measures energy.
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
15.37684 joules
How much heat is required to convert 0.3 kilogram of at 0 degrees C to water at the same temperature?
Measured in joules, the process would take 334,584 J to occur completely.
How do you find a mass of a substance dissolved in a solution given temperature and joules?
You can find the mass of a substance dissolved in a solution given temperature and joules using the relation q=mc(change in T). Where q is heat in joules, m is the mass, c is the specific heat capacity, and T is the temperature.
What is the unit used to measure thermal energy besides joules?
The answer is Temperature
During which process does water gain the most heat energy?
Evaporation because it requires 2,260 Joules to gain heat energy. Condensation, freezing, and melting require less Joules than evaporation.
