A 475 kg satellite is in a circular orbit at an altitude of 600 km above the Earth's surface. Because of air friction, the satellite eventually falls to the Earth's surface, where it hits the ground with a speed of 2.40 km/s. How much energy was transformed into internal energy by means of air friction

A 2.80-kg steel ball at 24.7°C is dropped from a height of 15.4 m into an insulated container with 4.50 L of water at 10.1°C. If no water splashes, what is the final temperature of the water and steel? The specific heat of steel and water is 450 J/(kg·K) and 4186 J/(kg·K) respectively.

A 2-kilogram [kg] projectile traveling at 100 meters per second [m/s] is stopped by being shot into an insulated tank containing 100 kilograms [kg] of water. If the kinetic energy of the projectile is completely converted into thermal energy with no energy lost, how much will the water increase in temperature in units of degrees Celsius [°c]?

A 0.0725 kg ice cube at −30.0°C is placed in 0.557 kg of 35.0°C water in a very well insulated container. What is the final temperature? The latent heat of fusion of water is 79.8 kcal/kg, the specific heat of ice is 0.50 kcal/(kg · °C), and the specific heat of water is 1.00 kcal/(kg · °C).

The rate at which a resting person converts food energy is called one’s basal metabolic rate (BMR). Assume that the resulting internal energy leaves a person’s body by radiation and convection of dry air. When you jog, most of the food energy you burn above your BMR becomes internalenergy that would raise your body temperature if it were not eliminated. Assume that evaporation of perspiration is the mechanism for eliminating this energy. Suppose a person is jogging for “maximum fat burning,” converting food energy at the rate 400 kcal/h above his BMR, and putting out energy by work at the rate 60.0 W. Assume that the heat of evaporation of water at body temperature is equal to its heat of vaporization at 100°C. (a) Determine the hourly rate at which water must evaporate from his skin. (b) When you metabolize fat, the hydrogen atoms in the fat molecule are transferred to oxygen to form water. Assume that metabolism of 1.00 g of fat generates 9.00 kcal of energy and produces 1.00 g of…

A 11.1 kg loose bag of soil falls 15.55 m at a construction site. If all the energy is retained by the soil in the bag in the form of heat, how much its temperature will increase

A 0.422 g food sample is used to raise the temperature of 14.656 g of water by 45.2 celsius. How many food Calories (kilocalories) of energy does the food contain per gram?

A thermally insulated sample of copper with mass equal to 100.0 g is at 30.0◦C. If 2500 J of energy is added to it by heat, what is the temperature of the copper? The specific heat of copper is 387 J/kg◦C.

Several containers filled with the same kind of ideal gas with the following masses and temperatures. Which box has the gas with the largest thermal energy? Box A 60 g -30°C O Box A Box D Box C O Box B Box B 50 g 0°C Box C 45 g 60°℃ Box D 35 g 100°C

A 75.0 kg concrete block falls off a 7.5 m tall wall. If all the initial energy of the concrete block is absorbed by itself when it hits the ground. What is the change in temperature of the concrete block (specific heat of concrete is 880 J/kg K)?
