State the theoretical physics model equation that relates pressure and temperature in the ideal gas model, and label in this equation what you are experimentally controlling and what you are experimentally measuring in activity 1?

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab. 

Aconductor easily transfer heat

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.

Ibelieve the answer is d. titaniumhope my answer has you : )
