Answer:
It will reduce
Explanation:
The time it will take to bake the cake will reduce when the temperature is increased by an additional 20°F .
Temperature change has a considerable effect on reaction rates since temperature is directly proportional to the average kinetic energy of reacting particles.
Generally reaction rate varies as temperature directly.
Therefore, the baking time will reduce as temperature increases.
Are ions or molecules identical formulas but distinct structures
Answer:
3
Explanation:
For an ideal ramp, M.A/V.R = 1 where M.A = mechanical advantage and V.R = velocity ratio.
Now, V.R = distance moved by effort, d'/distance moved by load, d = d'/d
Now, d' = 3 m and d = 1 m.
So, V.R = d'/d = 3 m/1 m = 3
From M.A/V.R = 1
M.A = V.R = 3
So, the ideal mechanical advantage of the ramp M.A = 3
Based on the phase diagram, the melting temperature of Q is 60°C, however the boiling temperature is not shown.
<h3>What is a phase diagram?</h3>
A phase diagram is a graph which shows the effect of pressure and temperature on the phase of a substance.
The melting or freezing point of a substance is that temperature in which the substance exists as both solid and liquid.
From the graph, the melting temperature of Q is 60°C.
The boiling or condensation point is temperature at which the substance exists as liquid and gas.
At the boiling point of a substance, its vapor pressure is equal to atmospheric pressure.
In the graph, the boiling temperature of Q is not shown clearly.

He contains the largest number; Fe contains the smallest number.
One mole of anything contains the same number (Avogadro’s number) of particles as one mole of anything else, so all we must do is decide which sample contains the most moles.
Moles = mass/molar mass or n = m/MM
Thus,
No. of atoms ∝ n ∝ 1/MM.
The element with the smallest molar mass, He, has the largest number of atoms.
The element with the largest molar mass, Fe, has the smallest number of atoms.
