Which individual would be the safest from a lightening strike? a. a person standing 8 miles away b. a person on a bike 8 miles away c. a person in a tent 8 miles away d. a person in a house 8 miles away

Option (d) is the correct answer.

Explanation:

During a lightening strike, when an individual is in a house 8 miles away then he will be safe.

This is because house is a closed shelter so lightening cannot enter inside the house unless and until the windows or doors are open.

Whereas a tent cannot be safe during lightening strike as tent is made up of cloth or light weight material. Hence, it does not provide any protection during lightening strike.

On the other hand, a person standing 8 miles away or  a person on a bike 8 miles away is not safe as both bike and ground are conducting in nature. So, it may lead to death if lightening strikes on it.

it takes on an electronical energy

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.
