Answer:
16.5 kwh and 59400 kJ.
Explanation:
kWh is a measure of energy that is equivalent to the power in kw times the number of hours the device worked.
In this case, it would be equal to:
![E_{kwh}=5.5kw*3h=16.5kwh](https://tex.z-dn.net/?f=E_%7Bkwh%7D%3D5.5kw%2A3h%3D16.5kwh)
1 kw also means 1kj of energy spent per second. With this, we calculate the amount of energy in kJ spent by the resistance:
![E_{kJ}=5.5\frac{kJ}{s}*3h*\frac{3600s}{1h} = 59400 kJ](https://tex.z-dn.net/?f=E_%7BkJ%7D%3D5.5%5Cfrac%7BkJ%7D%7Bs%7D%2A3h%2A%5Cfrac%7B3600s%7D%7B1h%7D%20%3D%2059400%20kJ)
Answer:
1, 2, and 3.
Explanation:
Hello.
In this process, since the phase transitions that require energy are those that pass from a state with less energy or more molecular order to a state with more energy or less molecular order, say, from solid to liquid (melting), from liquid to gas (boiling) and from solid to gas (sublimation), we can conclude that the arrows representing heat energy gained are 1, 2, and 3 since 1 represents boiling, 2 melting and 3 sublimation.
Best regards.
