What happens to temperature if matter is in a change of state?
During a change of state, such as melting or boiling, the temperature generally remains constant. The energy added or removed during the phase change is used to break or form intermolecular forces, rather than changing the kinetic energy of the particles to alter temperature. Once the change of state is complete, the temperature will then either increase or decrease again depending on whether heat is added or removed.
Does a fluid's density change when it is compressed and attenuated?
Yes it does change because its mass does not change but its volume does. When it is compressed the density will increase because its volume does. When it is attenuated will decrease because the volume does. Density is mass over volume. Remember: it only works because its mass stays the same and the volume changes.
When can you withdraw heat from something without decreasing its temperature?
When it is a crushed ice water mix. As long as there is water remaining, and there is mixing flow between water and ice, the temperature will not decrease, but the ratio of ice to water will increase as you withdraw heat.
What A steep slope on a phase-change graph indicates?
Different
What if your graph has two flat section joined by slope. What does it mean where the graph is flat On the graph mark when the ice is melting Also mark the boiling water.?
A graph with two flat sections joined by a slope represents a phase change. The flat sections indicate a constant temperature during a phase change, such as when ice is melting or water is boiling. The slope represents a temperature increase or decrease during the transition between phases. In a graph, you would mark the flat section for ice melting and boiling water where the temperature remains constant.
What happens to volume during phase changes?
Volume increases with increase in temperature, and decreases with decrease in temperature.
Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
How change will decrease the number of effective collisions during a chemical reaction?
An increase in temperature will lead to an increase in the kinetic energy of molecules, causing them to move faster and collide more frequently. This will result in more effective collisions during a chemical reaction.
Why does the temperature stay the same during a state change?
During a state change, such as melting or boiling, the energy being added or removed is being used to break or form intermolecular bonds rather than increase or decrease the kinetic energy of the particles. This leads to a plateau in temperature until the state change is complete.

The energy added or removed during the phase change is used to break or form intermolecular forces, rather than changing the kinetic energy of the particles to alter temperature. Once the change of state is complete, the temperature will then either increase or decrease again depending on whether heat is added or removed.
Why does the temperature increase and decrease during neutralization?
During neutralization, an acid and a base react to form water and a salt. This reaction is usually exothermic, releasing heat and causing the temperature to increase. As the reaction progresses and reaches completion, the temperature may then decrease as the system returns to equilibrium.
What happens to a substance's temperature as it god through the change of state?
During a change of state, the temperature of a substance remains constant. This is because the energy being added or removed is used to break or form intermolecular bonds rather than increase or decrease the substance's kinetic energy.
Does the temperature increase or decrease when energy is released during a chemical reaction?
The temperature increases when energy is released during a chemical reaction.
How will you judge whether a chemical reaction is exothermic or endothermic in nature?
A chemical reaction is exothermic if it releases heat to its surroundings, causing an increase in temperature. On the other hand, a reaction is endothermic if it absorbs heat from its surroundings, resulting in a decrease in temperature. This can be determined by measuring the temperature change during the reaction or by analyzing the enthalpy change of the reaction.
What is the relationship between enthalpy and temperature change during an adiabatic expansion process?
During an adiabatic expansion process, there is no heat exchange with the surroundings. As a result, the change in enthalpy is directly related to the change in temperature. When a gas expands adiabatically, its temperature decreases, leading to a decrease in enthalpy.
What two gases increase or decrease during inhlaing and exhaling?
Oxygen and carbon dioxide increase and decrease in the lungs.
Does the teperature drop or rise when a solid turns into a gas?
During the phase change, the temperature remains constant. Once the phase change is complete, the temperature will increase.
