Aglass containing 200.0 g of h2o at 20.0°c was placed in a refrigerator. the water loses 11.7 kj as it cools to a constant temperature. what is its new temperature? the specific heat of water is 4.184 j/g·°c.

Final temperature = 6.00 °C

Explanation:

The expression for the calculation of the enthalpy change of a process is shown below as:-

Where,  

 is the enthalpy change

m is the mass

C is the specific heat capacity

 is the temperature change

Thus, given that:-

Mass of water = 200.0 g

Specific heat = 4.18 J/g°C

Let final temperature be x °C

= -11.7 kJ  (Negative sign as heat is lost)

Also, 1 kJ = 1000 kJ

= -11700 J

So,  

Final temperature = 6.00 °C

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
