1 BTU is the energy required to heat 1 pound of water by 1 degree F. 1 Joule is defined mechanically, but in thermal terms it is 1/4.2 of a calorie (4.2 Joules/calorie), and 1 calorie is the energy required to heat 1 gram of water by 1 degree C. In fact 1 BTU = 1055 Joules.
The equivalent of about 6,330,000,000 joules or 6 million BTUs
what is the difference between elevation and leaching
What is the difference between dirt and dust?
None. Changing water from 25 degrees C to 5 degrees C requires heat to be REMOVED, not added!
the difference between a firth and a bay is a firth is bigger
The equivalent of about 6,330,000,000 joules or 6 million BTUs
627,600 joules is about 149,899.68 calories.
They are all measurements in the Unit of the Joule. The prefix Kilo means 1000, and the prefix Mega means 1,000,000. So one KiloJoule is 1000 Joules, and one MegaJoule is 1,000,000 Joules. The only difference is QUANTITY.
Well, unfortunately there are different BTUs, each a slightly different quantity of energy.The BTU (ISO) is 1054.5 joules exactly. Let's use that one, and avoid some rounding.10 kW = (10,000 joules/second) x (3,600 seconds/hour) x (1 BTU/1,054.5 joules) = 34,139.4 BTU/hour
Almost 90 % of electrical energy provided to an incandescent light bulb goes as heat and rest as light. A 100 Watt bulb puts out 100 Joules of heat per second. So - for one minute it would put out 6000 Joules (100 Watts X 60 seconds). 1 BTU (British Thermal Unit) of heat = 1055.056 Joules. So a 100 watt bulb, burning for one minute would put out 5.68 BTUs of heat. ( 6000 Joules / 1055.056 Joules) = 5.68 BTUs. Same bulb burning for one hour would generate 341 BTUs of heat.
A watt is a rate (speed) of using energy ... 1 joule per second.
internal energy change in words is the difference between the added energy and the original energy 100 - 60 = 40J
Heat is measured in BTUs (British Thermal Units)Further AnswerHeat is energy in transit from a warmer body to a cooler body, and, in the SI system is measured in joules(J). In the older, cgs system it was measured in calories. In the Imperial system it was measured in BTUs.
Energy due to temperature is called thermal energy and is measured in Calories or BTU. Kinetic energy is that due to motion of a body and is measured in Joules. There is an equivalence between thermal and mechanical energy, 1 Calorie = 4.2 Joules, 1 BTU = 1055 Joules
x BTUs / 3412.141633128 BTUs/KWH = KWH For example: -------------- If you burned 1,000,000 BTUs per month, then calculate the following: 1,000,000 BTUs / 3412.141633128 BTUs/KWH = ~293 KWHs per month Notes: ------- 1. Energy = the capacity/measure of a body/system to do work (expressed as the work that it does in changing to some specified reference state. It is measured in joules (SI units)). 2. 1 Joule = 1 Watt-second 3. 1 BTU = 1055.05585262 Joules (or Watt-seconds) 4. 1 WH (Watt-Hour) = 3.412141633 BTUs created/used in 1 hour = 3600 Joules or Watt-seconds (i.e. 1 Joule or Watt-second created/used every second for 1 hour) 5. 1 KWH = 1000 WH = 3412.141633 BTUs created/used in 1 hour = 3,600,000 Joules or Watt-seconds created/used every hour (i.e. 1000 Joules or Watt-seconds created/used every second for 1 hour) ======================================================== (1 KWH) = (1,000 watt-hour) = (1,000 joule / second) (hour) (BTU / 1055 joule) (3,600 sec / hour) = [ (1,000 x 3,600) / (1,055) ] [ joule - hour - BTU - second / second - joule - hour ] = 3412.3 BTU That's the amount of energy equivalent to 1 KWH . . . . . 3,412.3 BTU.
Voltage is electromotive force, in joules per coulomb. Power is energy transfer rate in joules per second, also known as watts.Not asked, but answered for completeness sake, and also to show the relationship between voltage and power, current is charge transfer rate in coulombs per second. So, if you multiply voltage (joules per coulomb) by amperes (joules per second) you get watts (joules per second).
The 7.75kg book as a PE of 113.93 joules and the 9.53kg book has a PE of 163.44 joules. A difference of 49.51 joules.
