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.

How many BTUs are generated per hour by a 10kW PV Solar Power Plant?

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


What is the difference in Joules in the gravitational potential energy of a 7.75 kg book that is 1.50 m above the ground and a 9.53 kg book that's is 1.75 m above the ground?

To calculate gravitational potential energy, the formula is PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height. In this case, the difference in potential energy between the two books is: PE = (m1gh1) - (m2gh2). Plugging in the values we have, we can calculate the difference in Joules.


Explain the difference between temperature and kinetic energy?

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


How many btu's of heat are produced by a T8 fluorescent lamp?

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.


How many volts in 1 Joule?

There is no direct conversion between volts and joules as they are different units measuring different quantities. Volts measure electric potential difference while joules measure energy.


What is the difference between voltage and power?

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).


What our the mechanics of changing btu to eletrical current?

To convert BTUs (British Thermal Units) to electrical current, you first need to convert BTUs to energy in joules, as 1 BTU is approximately 1,055 joules. Then, to find the equivalent electrical current, you use the formula ( P = IV ), where ( P ) is power in watts (joules per second), ( I ) is current in amperes, and ( V ) is voltage in volts. By rearranging the formula to ( I = \frac{P}{V} ), you can calculate the current based on the power derived from the BTU conversion and the voltage of your electrical system.


100 joules of heat plus to system of 60 joules of work?

The total energy added to the system is 160 Joules, comprising of 100 Joules of heat and 60 Joules of work. This increase in energy will lead to a rise in the system's internal energy.


What is the difference between Joules kilojoules and megaJoules?

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.
