<span>the electrons change their energy states and photons in visible spectrum (and infrared spectrum) are emitted.More the losses, more would be the light, but at the same time, more would be the heat generated.So
this necessitates that the metal used should have high resistivity (and
hence high losses), good thermmal conductivity and high melting point.
hope it helps

Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration
Explanation:
KOH is the limiting reagent
The molar ratio is 1:2
So if you have 6 moles of MgCl2 you need 12 moles of KOH
Answer:
277.7 g of CO2
Explanation:
Equation of reaction
C13H18O2 + 11O2 ---> 13CO2 + 9H2O
From the equation of reaction
1 mole of ibuprofen produces 13 moles of CO2
Molar mass of ibuprofen is 206g
Molar mass of CO2 is 44g
13 moles of CO2 weighs 572g
Therefore, 100g of ibuprofen will produce (100×572)/206 of CO2
= 277.7g
Answer:
A. The rate of heat transfer through the material would increase.
Explanation:
To calculate the heat transfer in a heat exchanger you decide that there is not heat leakage to the surroundings, that means that magnitude of the two transfer rates will be equal. Any heat lost by the hot fluid, is gained by the cold fluid. The equation that describes this is Q = m×Cp×dT
Where:
heat = mass flow ×specific heat capacity × temperature difference
So if we increase the rate of flow of cooling water and the other variables that ypu can control remain the same, the result is that the rate of heat transfer through the material would increase, as it is stated in option a.
