Calorimeter- an apparatus for measuring the amount of heat involved in a chemical reaction or other process.
When it has been disproven
Answer:
819 K
Explanation:
Given data
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial volume (V₁): 250 mL
- Initial temperature (T₁): 273.15 K (standard temperature)
- Final pressure (P₂): 0.500 atm
- Final volume (V₂): 1500 mL
- Final temperature (T₂): ?
We can find the final temperature using the combined gas law.
To determine the mass of the iceberg, we simply multiply the density with the volume. Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. Remember that the units should be homogeneous. We calculate as follows:
mass = density x volume
mass = 0.92 g /cm^3 ( 9470 ft^3) ( 30.48 cm / 1 ft )^3 ( 1 kg / 1000 g ) = 265.55 kg
