HOT AND COLD CAN PRESENTATION

MODIFICATIONSSomething we could do to change our outcome of the hot cans temperature is we could have wrapped it in

foil so the heat would stay in and with the cold can we could have isolated it in a room that was below room temperature and left it in there for the 30 minutes to

see if it would get colder

REAL LIFE EXAMPLES

A real life example of our project is when people get allergies they put paper towels over their faces to heat up and open their sinuses

TEMPERATURE CHANGE

The total temperature change in the hot can was 6.2 degrees Celsius. The total

temperature change of the cold can was 7.9 degrees Celsius.

CONTROLLED CAN COMPARISON

The temperature of our cold can in degrees Celsius the end was 34.3 degrees Celsius and the controlled cans final temperature was 33.4 degrees Celsius and the hot cans final temperature was 36.2 while the

controlled cans was 33.4 degrees Celsius
