The heat energy lost or gained by a substance is given by the equation
Q = mCΔT, where
Q is the heat energy gained or lost by a substance,
m is mass (in grams),
C is the specific heat of the substance,
ΔT is the change in temperature (final temperature - initial temperature).
The joules given off by 617 grams of water cooling from 65°C to 28°C, given the specific heat of water as Cw=4.186 J/g*Co, is:
Q = mCwΔT
Q = (617)(4.186)(28 - 65)
Q = -95562.194
Negative means heat is lost, so 96000 J of heat was lost.

<span>10 times as much. Since F=m*a, and a is constant, the only thing that affects force is the mass.
In response to the below answer, the acceleration due to gravity does not change. The force due to gravity definitely DOES change depending on the mass of the object. Since the force is what the problem asks for, the answer is 10</span>
answer: transverse and longitudinal
<u>Answer:</u>
For a. Neutrons and electrons also form an atom.
For b. The element is oxygen which is a non-metal and will form a negative ion while forming ionic bond.
<u>Explanation:</u>
There are 3 subatomic particles which form an atom. These are neutrons, protons and electrons.
Neutrons carry no charge, protons carry positive charge and electrons carry negative charge. Neutrons and protons are present in nucleus and electrons revolve around the nucleus.
The energy which is present between neutrons and protons are nuclear energy and the energy which is present between electrons and protons are electrostatic energy.
In an element, number of protons is always equal to the number of electrons. The atomic number is equal to the number of protons or electrons. The element which has atomic number 8 is Oxygen.
The electronic configuration of this element is
This element requires only 2 electrons to form a stable electronic configuration. An element which gains electron is considered as a non-metal and forms a negative ion because number of electrons increases.
