What else can I help you with?
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.
Is heat of combustion a chemical property of matter?
Yes, heat of combustion is a chemical property of matter. It refers to the energy released when a substance undergoes complete combustion with oxygen. It is specific to each substance and can be used to determine the energy content of fuels.
When ice melts it gains energy and is call this type of change?
When ice melts it is called a physical endothermic change.
What is unusual about the phase change of naphthalene?
Naphthalene undergoes a unique phase change called sublimation, where it changes directly from a solid to a gas without passing through the liquid phase. This property makes naphthalene useful for applications such as mothball production and as a sublimation dye in the laboratory.
What does the electron produce when they change energy levels?
When electrons change energy levels, they emit light or energy in the form of electromagnetic radiation. This emitted light can have specific frequencies or colors, depending on the difference in energy levels that the electron undergoes.
When matter undergoes change of state what does it absorb or release?
Energy.
What type of phase change does a substance absorb energy from its surroundings?
When a substance absorbs energy from its surroundings, it undergoes a phase change known as endothermic. This results in an increase in the substance's internal energy, allowing it to transition from one state to another (e.g., from solid to liquid or from liquid to gas) by absorbing heat from its surroundings.
What happens when a substance undergoes thermal expansion?
When a substance undergoes thermal expansion, its particles gain energy and move farther apart, causing the substance to increase in volume. This increase in volume is due to the increased average kinetic energy of the particles, leading to the substance taking up more space.
When concrete hardens it gives off thermal energy does the concretes temperature change?
Yes, when concrete hardens it undergoes an exothermic process which means it releases heat. This release of thermal energy can cause the temperature of the concrete to increase during the hardening process.
What property of a wave increases as the waves energy inceases?
An increase in energy corresponds to an increase in frequency or a decrease in wavelength.
What is positive change in thermodynamics?
a positive change is an increase in potential energy.
What property should you increase to increase the energy of an electromagnetic wave?
To increase the energy of an electromagnetic wave, you should increase its frequency. Energy is directly proportional to frequency for electromagnetic waves, according to the equation E=hf, where E is energy, h is Planck's constant, and f is frequency.
What property of a wave increase as the wave energy increase?
An increase in energy corresponds to an increase in frequency or a decrease in wavelength.
Why when the liquid is heated does the temperature not always increase?
If the liquid is heated to its boiling point, at which point it undergoes a physical change called vaporization, its temperature will not increase until the physical change is complete. This is due to the heat energy being used to break intermolecular bonds, such as hydrogen bonds, so that the physical change can take place.

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.

During Condensation which property does not change?
During condensation the kinetic energy, or temperature, does not change.
