They work by lowering the activation energy
Answer: The final temperature of nickel and water is .
Explanation:
The given data is as follows.
Mass of water, m = 55.0 g,
Initial temp, ,
Final temp, = ?,
Specific heat of water = 4.184 ,
Now, we will calculate the heat energy as follows.
q =
=
Also,
mass of Ni, m = 15.0 g,
Initial temperature, ,
Final temperature, = ?
Specific heat of nickel = 0.444
Hence, we will calculate the heat energy as follows.
q =
=
Therefore, heat energy lost by the alloy is equal to the heat energy gained by the water.
= -()
=
Thus, we can conclude that the final temperature of nickel and water is .
Answer:
its 303 Kelvin. (typing this for characters)
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure.
