Answer: Option (d) is the correct answer.
Explanation:
Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.
So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.
Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.
Answer:
B; Photosynthesis
Explanation:
Here, we want to get the process that helps produce glucose and oxygen
The process here is called Photosynthesis
It is the process by which green plants use chloropyhll iin them, catalyzed by sunlight to produce energy in form of glucose
PbH4 will be formed as a result of a polar covalent bond between the H and the Pb.
Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.
Based on this:
PbH4 would be expected to <span>have polar covalent bonds with a partial negative charges on the H atoms. </span>
We need to round to the ones place (which is a 7). We look to the digit to the right of the 7 and it is a number 5 or bigger (6), so we round the 7 up one to 8.
498 g
The 3 subatomic particles are : protons, neutrons and electrons.
Electrons mass = 0.0005
Electrons charge = negative
Protons mass = 1
Protons charge = positive
Neutrons mass = 1
Neutrons charge = neutral
