A student is investigating the effect of insulation on the rate of cooling of hot water in a 250cm
container
The student aan choose from the following apparatus
thermometar
250 cm glasbeaker
250 cm plastic beaker
250 cm copper dan
250 cm measuring cylinder
three different insulating materials
clamp, boss and stand
stopwatch
Plan an experiment to investigate the effectiveness of the three insulating materiale
You should
explain briefly how you would carry out the investigation,
slate the key variables that you would control,
diraw a table, or tables, with column headings, to show how you would display your readings.
You are not required to enter any readings in the table,
ekplain how you would use your readings to reach a conclusion.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
