How hot must the air in a balloon be heated if initially it has a volume of 750 L at 20 degrees celsius and the final volume must be 1000 L?
remains constant throughout the operation.
The only trick to this whole thing is to understand that
-- At constant pressure, volume is directly proportional to temperature.
Volume2/Volume1 = Temperature2/Temperature1
-- 'Temperature' means absolute temperature ... Kelvin, or (Celsius + 273).?
The initial temperature of 20 C is absolute temp of 293 K.
If the pressure remains constant, then
Absolute-temp2 = Absolute-temp1 x (Volume2/Volume1) = 1,000 x 293/750 = 3902/3 K.
°Celsius = Absolute - 273 = 117 2/3 ° C.
To find the temperature at which the air must be heated to increase the volume from 750 L to 1000 L, you can use the formula (V1/T1) = (V2/T2), where V1 is the initial volume (750 L), T1 is the initial temperature (20 degrees Celsius + 273 = 293 K), V2 is the final volume (1000 L), and solve for T2. Plug these values into the formula to find the final temperature needed.

What does water do as it is heated?
it will boil once it reaches 100 degrees Celsius
Is heated copper oxide a solid liquid or gas?
Copper(I) oxide has a melting point of 1201 degrees Celsius, and a boiling point of 2000 degrees Celsius. Copper(II) oxide has a melting point of 1235 degrees Celsius, and a boiling point of 2000 degrees Celsius.
If you started with water -10 degrees celsius describe what a thermometer would show if you heat it until it is over 110 degrees celsius?
The thermometer would show a gradual increase in temperature from -10 degrees Celsius as the water is heated. Once it reaches 0 degrees Celsius, the temperature will plateau until all the ice melts. Then, the thermometer will continue to rise above 0 degrees Celsius until it reaches over 110 degrees Celsius as the water boils.
What happens to lead when its heated from 0-2000 degrees celsius?
Lead undergoes a phase transition from solid to liquid as it reaches its melting point of 327.5 degrees Celsius. As the temperature increases further, the liquid lead will eventually vaporize into a gas at around 1750 degrees Celsius.
What happens to silver when heated?
When silver is heated, it will expand due to the increase in temperature. At high temperatures, silver will oxidize and form a black layer of silver oxide on its surface. If heated further, silver will eventually melt at a temperature of 961.78 degrees Celsius (1763.2 degrees Fahrenheit).
Which substance changes state when heated from 10 degrees Celsius to 80 degrees Celsius?
Water changes state from a liquid to a gas when heated from 10 degrees Celsius to 80 degrees Celsius.
What is the final volume of a balloon that was initially 500.0 mL at 25 degrees Celsius and was then heated to 50 degrees Celsius?
Change Celsius to Kelvin by adding 273.15. 25 C = 298.15 K 50 C = 323.15 K An equality. 500.0 ml/298.15 K = X ml/323.15 K 298.15X = 161575 X = 541.925 milliliters -------------------------------you do significant figures
When water at zero degree Celsius is heated its volume?
When water at zero degrees Celsius is heated, its volume initially decreases until it reaches its maximum density at 4 degrees Celsius. Beyond this temperature, as the water continues to heat up, it expands and its volume increases.
In which degree Celsius water heated?
100 degrees celsius
What happens to copper oxide when its heated?
if it is heated above 1200 degrees celsius than it melts
What state of matter is ethanol at 100 degrees celsius?
Ethanol is a liquid at 100 degrees Celsius. It boils at 78.4 degrees Celsius, so at 100 degrees Celsius it would be in a gaseous state if it were heated beyond its boiling point.
What is the unusual behavior of water as it is heated from 0degrees Celsius to 15 degrees Celsius?
1,000 m
What does water do as it is heated?
it will boil once it reaches 100 degrees Celsius
How many kilocalories were absorbed by the water iif you have 175g of water and it was heated from 15 degrees celsius to 88 degrees Celsius?
12.775 kcal
Is heated copper oxide a solid liquid or gas?
Copper(I) oxide has a melting point of 1201 degrees Celsius, and a boiling point of 2000 degrees Celsius. Copper(II) oxide has a melting point of 1235 degrees Celsius, and a boiling point of 2000 degrees Celsius.
What happens to chromium when heated at 20 degrees Celsius?
Nothing, a passivation occur.
What is the mercury's motion particles as it's heated from 45 degrees Celsius to 365 degrees Celsius?
As mercury is heated from 45 degrees Celsius to 365 degrees Celsius, its particles will gain energy and move faster. This increased thermal energy causes the particles to vibrate more quickly and spread out, leading to an expansion in volume. At the higher temperature, the motion of mercury particles will be more rapid and chaotic compared to when it was at 45 degrees Celsius.
