What else can I help you with?
During a temperature change what is happening to the substance?
A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
What occurs during both melting and freezing?
During both freezing and melting, you have a phase change.
The particle with two protons and two neutrons ejected during decay?
Alpha particle
What is a particle with two neutrons and two protons ejected during decay?
an alpha particle
During melting, what two states of matter are present?
During melting, both the solid and liquid states of matter are present.
What happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
How can a solid be melted using the particle theory?
According to particle theory, a solid can be melted by increasing the temperature, which adds energy to the particles. As the temperature rises, the particles vibrate more vigorously, overcoming the forces that hold them in fixed positions. Once enough energy is supplied, these particles can break free from their organized structure, transitioning the solid into a liquid state. This process illustrates the changes in particle movement and arrangement during melting.
A change of what occurs during both freezing and melting?
A change of solid occurs during both freezing and melting.
A substance has a melting point of 14c and a boiling point of 78c in what state is the substance at 78c?
The substance would be in a liquid and gas state, this would be due to vaporization that is happening during boiling.
What happens to a water particle during precipitation?
During precipitation, a water particle is released from the clouds. This particle can be in the form of a water droplet of rain, sleet, snow, freezing rain or even hail.
What kind of charge does the particle emitted from the nucleus during betta - decay have?
The particle emitted during beta- decay is an electron, therefore it has a negative charge.
A change of occurs during both freezing and melting?
A change in temperature occurs during both freezing and melting. Freezing and melting are physical changes since the chemical contents of the matter do not change.
