An electrical heater raises the temperature of a measured quantity of water. Six thousand joules of energy is absorbed by the water from the heater in 30.0 seconds. How many units of energy heater will consume in a month of 30 days when it works for five hours daily.
Answers
Answer:
Electrical Energy = Power x Time. The total amount of electrical energy used depends on the total power used by all your electrical devices and the total time they are used in your home. One kilowatt hour is equal to 1000 watts of power used for one hour of time.
Answer:
Based on the provided data, we must first determine how much energy the electrical heater uses per second in order to determine how much it will use in a month.
We are aware that in 30.0 seconds, the heater absorbed 6,000 joules of energy. As a result, we can determine the amount of energy absorbed each second as follows:
Energy per second = Energy absorbed / Time taken
Energy per second = 6,000 J / 30.0 s
Energy per second = 200 J/s
Explanation:
This means the heater uses 200 joules of energy per second.
Then we must figure out how much energy the heater will use in five hours, which is the daily usage time. Because there are 30 days in a month, the total number of hours used by the heater in a month is:
Total monthly hours = Hours per day x Days per month
Total number of hours in a month = 5 x 30
Total monthly hours = 150
As a result, the heater will be used 150 hours in a month.
To determine the total energy consumed by the heater in a month, multiply the energy consumed per second by the total number of seconds used in a month:
Total energy consumed = Energy per second multiplied by the number of seconds in a month
Total consumed energy = 200 J/s x 150 hours x 3600 s/hour
1.08 x 109 J = total energy consumed
As a result, the electric heater will use a total of 1.08 x 109 joules of energy per month.
