One kilojoules is equal to 1000 joules:1kJ = 1000JThe energy E in joules (J) is equal to the energy in kilojoules (kJ) times 1000:E(J) = E(kJ)× 1000ExampleConvert 4kJ to joules.The energy E in joules (J) is equal to 4 kilojoules times 1000:...
As it happens, if you add a given amount of heat (Q) in joules to a system, or remove heat from that system, you can determine how much the system's temperature will change (∆T) in Celsius as long as you know the mass of the system (often a sample of water)min grams and it...
Converting units can be difficult, so when doing so it is important to remember to write down your computations step by step and to label all units. Joules (J) and calories, the derivative units of kilojoules (kJ) and kilocalories (kcal), are both used to measure energy. Keep in mind ...
How to convert joules to BTU How do you convert grams into atomic mass unit? Calculate the osmotic pressure of a solution containing 25.8 g of glycerin (C3H8O3) in 261.5 mL of solution at 315 K. Express your answer in atmospheres to three significant figures. ...
Answer to: In my Bio Lab class we have to convert each value into the designated units. How do you convert 46,756,790 mg into kg? By signing up,...
In science, we say you have to do work against the force of gravity to push the boulder up the hill. Doing work means you have to use energy: the muscles in your body have to convert sugar and fat to make the energy you need to push the boulder. Where does this energy go?
You can measure sizable amounts of household energy using the therm, which is equivalent to 100,000 British thermal units. When measuring the energy from natural gas, however, you can also use cubic feet. To produce 1 therm of energy, you need to use abo
a 10-nanosecond pulse has an energy content of only 10 joules. To put this in perspective, the average microwave oven in one second generates 1 kilojoule, or thousand joules of energy. It typically takes about 4 minutes to boil a cup of water, which corresponds to 240 kilojou...
How are heat joules measured? How can you determine the heat capacity of your calorimeters? A. By heating water, measuring the temperature difference and multiplying it with the specific heat of water and the weight of water B. B Use the specific heat of water to determine...
How much kilojoules of energy are needed to heat 140 g of water from 15 deg-C to 71 deg-C? The heat capacity of lead is 0.13 J / g C. How many joules of heat would be required to raise the temperature of 15 g of lead from 22 degrees C to 37 degrees C? How do I calculate...
