Rose reviews the EPA website and finds a recommendation to use cold tap water for cooking instead of starting with warm water from the tap. Why does the EPA site suggest using cold tap water for cooking instead of starting with warm tap water?

The Environmental Protection Agency suggests using cold tap water for cooking instead of starting with warm tap water is because our drinking water is made out lead pipes, which is a serious risk to health.

Explanation:

Lead is found throughout  the environment in lead found in paint, air, soil,   food and water.Lead can pose  a significant risk to your health  if too much of it enters your body.   Lead enters drinking water primarily  as a result of the corrosion.It also contains in materials containing lead like in the water distribution system and   household plumbing.Lead in drinking rarely cause of lead poisoning can significantly increase a person’s total lead exposure. In particular the exposure of infants who drink baby formulas  and concentrated juices that are  mixed with water. EPA estimates  that drinking water can make up  to 20% or more of a person’s  total exposure to lead which is dangerous.

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

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.
