What weighs more 2000 pound of rice or 2000 of steel? meaning they are the same.
To make the barrel of water weigh 12 pounds, you would need to remove 8 pounds of water from the barrel.
Yes, boiling water to make steam is a physical change. This is because the water undergoes a change in state from liquid to gas without any change in its chemical composition.
That converts to 4000 pounds which is the same as 2 tons. Pounds is a unit of mass/weight. Gallons is a liquid measure. They do not convert cleanly. The density of the liquid being measured can make a big difference. If the liquid is water, there is 8 pounds to a gallon.
There are several ways to heat water until it steams. Electric heating elements will do the trick, as will burning something like coal, oil, wood etc. Even intense sunlight can boil water.
To make steam and generate electricity, you usually burn fossil fuels like coal, natural gas, or oil in a power plant. The heat produced from burning these fuels is used to turn water into steam, which then drives a turbine connected to a generator to produce electricity.
One gallon of water weighs approximately 8.34 pounds. When water is converted to steam, it expands significantly; specifically, one pound of water can produce about 1,600 gallons of steam at atmospheric pressure. Therefore, 1 gallon of water can produce around 13,440 pounds of steam when fully vaporized.
Fire+Water=Steam
No. Steam is just water.
No, boiling water to make steam is a physical change, as it can be reversed by cooling the steam back into water. The water molecules remain the same substance throughout the process.
To calculate the amount of energy required to produce steam, we need to know the specific enthalpy of water and the temperature/pressure conditions. Generally, it takes about 1,000 BTUs to convert 1 pound of water at 212°F to steam. Therefore, for 32 million pounds of steam, it would require approximately 32 million BTUs, or 32,000 MMBTUs (using the conversion that 1 MMBTU = 1,000,000 BTUs).
I know for a fact that on the Iphone it is metal (stone+fire) and steam (air+water)
You don't.
Ice, or steam
water+fire
Steam+water
To make distilled water at home, you can boil water in a pot and collect the steam in a clean container. As the steam cools, it will condense back into pure distilled water.
