Hand disinfection is frequently recommended for prevention of transmission of the rhinovirus that causes the common cold. A total of 212 volunteers were assigned at random to enter the hand-sanitizer group (HL+, which used the sanitizer every three hours or after handwashing) and the control group which was asked to use routine hand washing but avoid alcohol-based hand sanitizers.
Yes(infection) no(infection)
HL+ 49 67
Control 49 47
Do the data give good evidence that the above hand sanitizing practice reduced the chance of getting the common cold?

Heat transfer is strictly the transferring heat from one body to another and is limited only to heat, thermodynamics also includes conversion to and from heat energy into another type of energy and the transfer of heat as well
