Generally the metal of container is made up of such material that it will absorb heat and distribute it on the surface so that the temperature can rise and it will help to cook the food
But the handle of the container is used to hold it and we need not its temperature to be vary high so the handle must be made up of different material which will not absorb too much heat and its temperature will not rise to high value so that we can hold it easily
so here most appropriate option is given as
<em>D) The metal in the handle can absorb more energy without changing temperature as easily as the metal in the pot.</em>
Answer:
The time is 0.713 sec.
Explanation:
Given that,
Weight of water = 4 liters
Initial temperature = 128°C
Power = 1400 Watts
Final temperature = 708°C
Weight = 1.1 kg
Specific heat of steel = 0.46 kJ/kg°C
Specific heat of water = 4.18 kJ/kg°C
We need to calculate the heat gained by bucket
Using formula of heat
Put the value into the formula
We need to calculate the heat gained by water
Using formula of heat
Put the value into the formula
We need to calculate the total heat
Using formula of heat
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time is 0.713 sec.
It's B.
It's never going to be true UNLESS you cooled the entire thing to below zero then it could be true.
Answer:
The product of the decay its Sulfur-32
Explanation:
Phosphorus-32 ( lets write it , where the number above its the atomic mass and the number below the atomic number) decays turning a neutron into a proton and emitting radiation on the form of a electron. This is the beta minus decay, and, actually, an electronic antineutrino its also produced. We can write this decay for an X isotope with a Y isotope produced as:
where its the electron, and the electronic antineutrino . We can see that the atomic number increases by one (cause a proton it produced and retained into the nucleus), and the atomic mass is approximately the same (there is a small difference between the neutron and proton mass, but its very small).
So, Phosphorus-32 (atomic number 15) will turn to an element with atomic number 16, and atomic mass 32, as:
.
.
The Y isotope must have an atomic number of 16 and an atomic mass of 32. The element with atomic number 16 its Sulfur (S), so, our decay its
.
and the product of such decay its Sulfur-32
