When a certain ideal gas thermometer is immersed in a water-ice mixture at 273.15 k, the mercury level in the right arm is 102 mm above the reference mark. when this thermometer is then immersed in a liquid of unknown temperature, the mercury level is 21 mm above the reference mark. what is the temperature of the liquid?

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.

What’s the kinetic energy of the object? use . erica is competing in the shot put event at a track meet. she hurls a shot with a mass of 4 kilograms at a speed of 9 meters/second. the shot’s kinetic energy is joules.
