TheEffect of Type of Insulation Wrap on Temperature of Water
Thistopic will explore the relation of insulated jars with differentmaterial. The change in temperature will observed and recorded andthen later on the difference is compared. Any material that will heatwater to highest degree Celsius with be considered to the bestinsulator while the one which will heat the water in less temperaturewill be considered to be poor insulators.
H0:There is no effect of water in sun are wrapped with difference typeof insulation then the temperature of water will not increase
Dependentvariable and how they are measured.
