Jessica places 100. g of water at 20.0℃ in an insulated cup. The specific heat capacity of water is 4.18 J/(g℃). What is the final temperature of the water if 5000. J of energy is added to the water in the insulated cup?

31.96°C

Explanation:

Given that,

Mass of water, m = 100 g

Initial temperature,

The specific heat capacity of water is 4.18 J/(g℃)

We need to find the final temperature of the water if 5000. J of energy is added to the water in the insulated cup.

The heat added to the water is given by :

So, the final temperature is 31.96°C.

answer; economic order quantity;

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
