A 200g of gas was heated from 50°C to around 120°C. The gas expanded in a piston-cylinder apparatus from 2.0L of initial volume to find a volume of 10.0L against an external pressure of 3.0 atm. Calculate for the change in the internal energy. The specific heat of water is 2.19 J/g×°C)
Calculate the specific heat capacity of a new alloy if a 15.4g sample absorbs 393 J when it is heated from 0.0°C to 37.6°C
When gasoline burns in an automobile engine, the heat released causes the product CO2 and H2O to expand,which pushes the piston outward. if the expanding gases do 789 J of water on the piston and the system loses 245 J of heat, calculate "\\Delta U" in J
Neutron stars are some of the densest objects in the universe. They form during supernova ex plosions and are very small compared to other astronomical objects. You can assume 5 * 10 ^ 17 kg/m³ as the average density of a neutron star. The Earth has a total mass of about 5.97*10^ 24 kg
What would be the diameter of the Earth if it had the density of a neutron star?
