Solved Bulunuz Determine The Amount Of Energy Needed To Chegg Determine the amount of energy needed to | chegg bulunuz. determine the amount of energy needed to arrange four point charges q1,q2,q3 placed at a,b,c. Determine the minimum amount of energy needed to move a satellite from its orbit around the earth to an infinite distance from the earth. the mass of the satellite is 8.75 x 10^3kg and its orbital radius is 6.90 x 10^6 m. take the mass of the earth to be 5.97 x 10^24. there are 2 steps to solve this one.
Solved Question 4 5 Pts Determine The Amount Of Energy Chegg Example #2: calculate the amount of energy in kilojoules needed to change 207.0 g of water ice at −10.0 °c to steam at 125.0 °c. the following constants for water may be helpful. We can use heat = mcΔt to determine the amount of heat, but first we need to determine Δt. because the final temperature of the iron is 73.3°c and the initial temperature is 25.0°c, Δt is as follows: Δt = t final − t initial = 73.3°c − 25.0°c = 48.3°c. Luckily, our water heating calculator takes care of it for you! if you know the efficiency and the power of the heater, you can also compute the time required to reach the final temperature. the formula is: \text {time} = \frac {q {\text {total}}} {\text {efficiency} \times \text {power}} time = efficiency × powerqtotal. where:. Example #5: how much energy in kj is needed to heat 5.00 g of ice from −10.0 °c to 30.0 °c? the heat of fusion of water is 6.02 kj mol, and the molar heat capacity is 36.6 j mol k for ice and 75.3 j mol k for liquid water.
