The heat is exchanged when two different temperature objects come in contact. The energy gained by an ice block is 2.3 Joules.
<h3>What is temperature?</h3>
Temperature is the degree of hotness and coldness of the object.
A 7g block of ice was added to a coffee cup full of 103.4 grams of water. The water had an initial temperature T₁ = 24.5 C and a final temperature T₂ = 19.2 C after all the ice had melted.
Heat lost by water = Heat gained by ice
Qgain = ms(T₂ -T₁ )
Substituting the value for mass of water m =103.4 g= 0.1034 kg , specific heat of water s = 4.18 kJ/kg and temperature values, we get
Qgain = 0.1034 x 4.18 x (24.5 - 19.2) 
Qgain = 2.3 Joules
Thus, the energy gained by an ice block is 2.3 Joules.

We want to know what does the fact that Mercury has no atmosphere tell us. Since Mercury has no atmosphere it cant reflect a lot of sunlight that is hitting its surface. Its constantly being hit by solar wind. So Mercury reflects a small percentage of the sunlight that strikes it. 
        
                    
             
        
        
        
Answer:
Temperature at the exit = 
Explanation:
For the steady energy flow through a control volume, the power output is given as
 
Inlet area of the turbine = 
To find the mass flow rate, we can apply the ideal gas laws to estimate the specific volume, from there we can get the mass flow rate.
Assuming Argon behaves as an Ideal gas, we have the specific volume 
as 


for Ideal gasses, the enthalpy change can be calculated using the formula 

hence we have


<em>Note: to convert the Kinetic energy term to kilojoules, it was multiplied by 1000</em>
evaluating the above equation, we have 
Hence, the temperature at the exit = 
 
        
             
        
        
        
The fatal current is 51 mA = 0.051 Ampere.
The resistance is 2,050Ω .
Voltage = (current) x (resistance)
            =  (0.051 Ampere) x (2,050 Ω)  =  104.6 volts .
==================
This is what the arithmetic says IF the information in the question 
is correct.
I don't know how true this is, and I certainly don't plan to test it, 
but I have read that a current as small as  15 mA  through the 
heart can be fatal, not  51 mA .
If 15 mA can do it, and the sweaty electrician's resistance is 
really 2,050 Ω, then the fatal voltage could be as little as  31 volts !
The voltage at the wall-outlets in your house is  120 volts in the USA !
THAT's why you don't want to stick paper clips or a screwdriver into 
outlets, and why you want to cover unused outlets with plastic plugs 
if there are babies crawling around.
