Calculate the heat given to a 500g steel containing 450g of water to raise the temp from 25degrees Celsius to 100The specific heat capacity of steel.510 Steel and water have the same temp changes?
The water and pot(/) have a temperature increase of 100-25 degrees C that is 75 degrees. the formula Q=mass * SH* change in temperature can be used for both the water and the steel pot Hence for steel pot Q=510 j/kg/degC*.5kg*75Deg C=19125 joule. For water SH=4187 j/kg/C QW= .45*4187*75=141311 joule total heat (neglecting changes and losses to get the water to 100 deg C is 160436 joule or 160.4 kjoule. Note this does not boil the water it only raises the temperature to 100 degrees C. to boil the water requires approximately a futher 1250 kJ
What mass of water can be heated from 25 degrees celsius to 5 degrees celsius by the addition of 2825 joules?
None. Changing water from 25 degrees C to 5 degrees C requires heat to be REMOVED, not added!
In a car accident 500 g of sodium azide in the air bag decomposes to form 323.20 g of nitrogen gas and some sodium metal How much sodium metal is produced 100g 176.80g 323.02g or 500g?
The amount of sodium metal produced can be calculated using the law of conservation of mass. The total mass of products (nitrogen gas and sodium metal) should equal the initial mass of sodium azide. In this case, 500g of sodium azide decomposes to form 323.20g of nitrogen gas and 176.80g of sodium metal. Therefore, 176.80g of sodium metal is produced.
Can a nickel be used to calibrate a digital scale?
You will need more than just one nickel. Most scales require you to calibrate with a specific weight, usually a weight that is close to the scales capacity (ie 500g weight for 500g capacity scale) Nickels weigh approximately 5g so you would needs lots of them. However it is not exact and you will sometimes find nickels that weigh 4.9g to 5.1g. Nickels should only be used as a last ditch effort to fix a scale that is way out of calibration. You can find cheap calibration weights for pocket scales online.
What it iodine worth?
The price of iodine can vary depending on the form and purity. As of May 2021, the average price for a 500g bottle of iodine flakes is around $30-50. Industrial-grade iodine typically costs less than pharmaceutical-grade iodine due to differences in purity and quality.
How much heat in a k cals must be added to 0.5kg of water at 20 degrees celsius to raise its temperature to 50 degrees celsius?
The specific heat capacity of water is 1 calorie/gram°C. Since 0.5kg of water is 500g, the total heat required would be (500g)(30°C)(1 cal/g°C) = 15,000 calories. So, 15,000 calories (kcal) of heat must be added to raise the temperature of 0.5kg of water from 20°C to 50°C.
How many cc of h2o is needed for 500g?
At standard temperature and pressure, water has a density of 1 gram per cubic centimeter, so 500 grams would be 500 cc (or 500 ml).
Does 500g of water occupy a space of 50ml?
Yes, 500g of water occupies a volume of 500ml, as 1g of water is equivalent to 1ml. Therefore, the volume of 500g of water is 500ml, not 50ml.
How much water weights 500g?
im guessing about 500g worth?
How do you calculate the density of water?

How many 500g bags are needed to fill a 12kg bag?
24g
How much water does it take to make a 500g steak?
Producing a 500g steak typically requires about 5,000 to 7,000 liters of water, depending on various factors such as the farming practices and the type of feed used for the cattle. This figure includes water used for drinking, feed production, and processing. The high water footprint is primarily due to the resources needed for raising livestock and growing feed crops.
What is the different between 1kg and 500g?
1 kg - 500g = 500g
What is 4.72kg-500g?
