in a lab experiment to test the change in temperature of NaCl and the change in temperature of water:

Specific heat of NaCl is 0.88
specific heat of DI water is 4.2

in the experiment, the change in temperature for the water was greater than the change in temperature of the table salt.

why did this occur?

Answer #1

specific heat is,the amount heat required to raise 10C of 1 gram of substance .specific heat of water if high and specific heat of water is called calorie.incase of water , when heated,the friction hydrogen bonding happend (means the breaking of hydrogen bonding) and,some of the heat energy wil be used to overcome their actuall kinetic energy of individual molecule in water.

where as in NaCl the bonding is ionic and needs less amount of heat to break.water needs more heat to break hydrogen bonds and hence water has greater specific heat than NaCl

When 7.56 g of NaCl is added to a coffee cup calorimeter, the water temperature changes by 4.1 ºC. If the heat of solution (the enthalpy change upon dissolving in water) is 3.8 kJ/mol, what mass of solution must be in the cup? Assume the specific heat capacity of the solution is the same as the specific heat capacity of water.

Experiment: Add 1/8 test tube chlorobenzene and 1/4 test tube water to a 100mm test tube. If the chlorobenzene rests on top of the water, tap the test tube to make it fall to the bottom. Add 0.7 g of salt and stopper and rock until it all dissolves. Let it stand for a minute to clear. Questions: 1) Which layer is on the bottom? (from my experiment I got that chlorbenzene was at the bottom) 2) Explain why. (Which...

A student wants to determine the specific heat of NaCl. He weighs out 50 g of NaCl at 10 ºC and adds it to 100. mL of water at 30 ºC. The final temperature of the solution is 24.5 ºC. The student calculates that the specific heat of NaCl is 3.17 J/gK, but the instructor tells him that value is not correct. Why is this answer incorrect?

This cow is standing in the sea. Even though the air temperature and the ocean temperature today are coincidently the same value of 300K, this cow experiences the water as feeling colder than the air. This is because: a) the specific heat of water is less than that of air. b) the latent heat of vaporization of the cow is higher than air but lower than water c) the specific heat of water is greater then that of air. d)...

a coffe cup calorimetry experiment was performed in a general chemistry class. Two lab partners added 78.9g of lead initally at a temperature of 102.1 degrees celcuis, to a sample of water in a coffee-cup calorimeter. the water in the calorimeter startedout at 22.9 degrees celcuis, once the temperature of the water and the metal equilibrated the final temperature of both was 24.3 degree celcuis. Calculate the mass of water that must have been in their calorimeter. The spefific capacity...
