What will happen to the state of the substance the atomic or molecular activity and the shape of the graph when thermal energy is added?
When thermal energy is added to a substance, the atomic or molecular activity will increase, leading to higher kinetic energy of the particles. This results in the substance changing states from solid to liquid, and then to gas, if the temperature continues to rise. The shape of the graph will show an increase in temperature with corresponding changes in state, known as phase transitions.

What will happen to happen to the state of the substance the atomic or molecular activity and the shape of the graph when thermal energy is added?
When you add thermal energy you are going to do two things: you will cause a progressive change of phase from solid to liquid to gas to plasma, and you will raise the temperature causing increased atomic/molecular activity. Unless you identify the axes of the graph, I don't know what graph you are talking about and can't talk about the shape of whatever it is you are graphing.
Do all objects have thermal energy?
Yes, all objects have thermal energy because it is a form of kinetic energy associated with the random motion of particles at the atomic and molecular level. The amount of thermal energy an object has depends on its temperature.
Are people thermal energy?
No, people generate and emit thermal energy as heat through metabolic processes, but they are not considered thermal energy themselves. Thermal energy is a form of kinetic energy associated with the motion of particles at the atomic or molecular level, which people possess due to the movement of molecules in their bodies.
Which substance wood or silver is the better thermal conductor?
Silver is a better thermal conductor than wood. Silver has a higher thermal conductivity due to its atomic structure, allowing heat to flow through it more easily compared to wood which has a lower thermal conductivity.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
When an object gains thermal energy, the motion of its molecules increases, leading to faster movement and higher kinetic energy. This can result in the object heating up. Conversely, when an object loses thermal energy, the motion of its molecules decreases, leading to slower movement and lower kinetic energy, resulting in the object cooling down.

What is molar atomic mass?
The atomic (molecular) weight of a substance is its molar mass.
Predict what will happen to the state of the substance the atomi and molicular activity?
As the substance undergoes an increase in temperature, its atomic and molecular activity will also increase. This will result in the particles moving faster and having more energy, potentially leading to a change in state if the substance reaches its melting or boiling point.
What the molecular mass of MgF2?
The Atomic Mass of Mg is 24. The atomic mass of fluorine is 19. Therefore the relative mass of the substance is 62.
What is the molecular formula of silver?
Ag is the molecular formula for silver. If you look on a periodic table, you will find this substance with the transitional metals and with the atomic number of 47.
What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
Explain why two substance can have the same temperature but different amounts of thermal energy?
Because energy is related to the atomic mass of the substance (1/2 mv^2 and all that). So, at the same temperature a more massive substance has a greater thermal energy.
How do you convert ppm into gpg?
To convert parts per million (ppm) of a substance to grains per gallon (gpg), you need to know the atomic or molecular weight of the substance. Once you have this information, you can use the formula: gpg = ppm x (atomic/molecular weight/7000).
What is the heat in the substance really a measure of?
Heat is a measure of the molecular and atomic excitation of the substance, i.e. the degree of vibration that it has available to impart to other substances that it comes into contact with.
Do all objects have thermal energy?
Yes, all objects have thermal energy because it is a form of kinetic energy associated with the random motion of particles at the atomic and molecular level. The amount of thermal energy an object has depends on its temperature.
How does solar energy goes from electromagnetic energy to thermal energy?
When photons (light particles) are absorbed by a substance, the energy of the photon is converted into kinetic energy among the atoms within the substance. As the atomic kinetic energy (motion) within a substance rises, so too does the temperature (thermal energy) of that substance.
How can one determine the theoretical mass of a substance?
To determine the theoretical mass of a substance, one must calculate the molecular weight of the substance by adding up the atomic weights of all the atoms in its chemical formula. This can be done using the periodic table to find the atomic weights of each element present in the substance.
