5) Show that Q total in cal is needed to change 50 g of 0 ̊C ice to steam at 100 ̊C. (a) Show that Q in cal, Quantity of heat is needed to increase the temperature of 50 g water from 0 ̊C to 100 ̊C. The specific heat capacity for water is 1 cal/g•̊C. (b) Show that Q in cal, Heat of fusion is needed to melt 50 g of 0 ̊C ice. The heat of fusion Lffor...
Circle answers please A thin, cylindrical rod l = 20.8 cm long with a mass m = 1.20 kg has a ball of diameter d = 6.00 cm and mass M = 2.00 kg attached to one end. The arrangement is originally vertical and stationary, with the ball at the top as shown in the figure below. The combination is free to pivot about the bottom end of the rod after being given a slight nudge. m (a) After the...
A glass tumbler of 200 g mass and 5 cm inside diameter is filled to a depth of 10 cm with tap water whose temperature is 10 degrees C, and at 50 g of ice 0 degrees C are then added. At the end of an hour, it is noticed that the ice has just finished melting. What was the average rate, in calories per second, at which heat flowed into the glass from its surroundings?
A wooden block of volume 5.26 times 10^-4 m^3 floats in water, and a small steel object of mass m is placed on top of the block. When m = 0.400 kg, the system is in equilibrium and the top of the wooden block is at the level of the water. (Take the density of steel to be 8 g/cm^3.) (a) What is the density of the wood? kg/m^3 (b) What happens to the block when the steel object is...
finish all of them and show process (g) What is the volume of the oil displaced by the block, in terms of the variables of the problem? Vo= Problem 2 - Pressure and Buoyancy with Oil and Water You have a block of a light wood that is 10 cm by 10 cm by 10 cm. You also have a bucket that you fill with a depth of 20 cm of water (has a density of 1000 kg/m'), and then...
