Asmall electric heater, immersed in 80g of water in a calorimeter of 40j/k raises the temperature from 10.5 degree celsius to 25 degree celsius in 12 minutes. using the same apparatus with 50g of oil instead of water, it is found that the temperature of oil rises from 7 degree celsius to 27 degree celsius in 10 minutes. find specific heat capacity of the oil.

The lid of a pressure cooker forms a nearly airtight seal. steam builds up pressure and increases temperature within the pressure cooker so that food cooks faster than it does in an ordinary pot. the system is defined as the pressure cooker and the water and steam within it. if 2.0 g of water is sealed in a pressure cooker and then vaporized by heating, and 5127 j must be added as heat to completely vaporize the water, what is the change in the system’s internal energy? answer in units of j.

For a final project in seon’s physics class, students were instructed to build a water balloon launcher, write a hypothesis, and then carry out an experiment with the launcher. considering that 90 degrees means launching the balloon straight up into the air and 0 degrees means launching it straight along the ground, seon first wrote the hypothesis below.if the angle at which the balloon is launched decreases from 90 degrees, then the distance that the balloon goes along the ground will increase, because more energy will go into pushing the balloon forward than upward.seon found that this was true until the angle reached about 45 degrees, and then the distance along the ground began to decrease again. seon knows that he will need to write a new explanation, but he would like to conduct an experiment that is based on his original hypothesis, with one of the variables changed.how could seon rewrite his hypothesis to be a statement that will more likely be supported? change the independent variable to “if the angle at which the balloon is launched increases up to 90 degrees . .”change the dependent variable to “if the angle at which the balloon is launched moves closer to 45 degrees . .”change the independent variable to “if the angle at which the balloon is launched moves closer to 45 degrees . .”change the dependent variable to “if the angle at which the balloon is launched increases to 90 degrees. .”
