Answer:
T_finalmix = 59.5 [°C].
Explanation:
In order to solve this problem, a thermal balance must be performed, where the heat is transferred from water to methanol, at the end the temperature of the water and methanol must be equal once the thermal balance is achieved.
where:
mwater = mass of the water = 0.4 [kg]
Cp_water = specific heat of the water = 4180 [J/kg*°C]
T_waterinitial = initial temperature of the water = 85 [°C]
T_finalmix = final temperature of the mix [°C]
Now replacing:
Answer:
The change in temperature is
Explanation:
From the question we are told that
The temperature coefficient is
The resistance of the filament is mathematically represented as
Where is the initial resistance
Making the change in temperature the subject of the formula
Now from ohm law
This implies that current varies inversely with current so
Substituting this we have
From the question we are told that
Substituting this we have
=>
