Heat breaks and creates bonds between particles in a a physical change b chemical chage c change of state or d change of temperature?
Heat breaks and creates bonds between particles in a chemical change. Heat energy is often required to break existing bonds between atoms or molecules and to form new bonds, leading to a rearrangement of atoms and the creation of new substances with different chemical properties.
Why does not the temperature change during change of state from solid to liquid?
Addition of heat produces more liquid, breaking apart the intermolecular bonds, rather than increasing bond oscillation (increasing temperature).
What do you think will happen to the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
Energy is neither created nor destroyed in a chemical reaction Explain where the energy released or absorbed by the reactions comes from or goes to?
Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.
What are two examples of change that is not caused by energy and explain?
One example is a phase change, such as ice melting into water, where energy is used to change the state of the substance without altering its temperature. Another example is a chemical reaction where the bonds between atoms are broken and rearranged without a change in energy, resulting in a new substance.
What can break chemical bonds of atoms?
A chemical reaction can break the chemical bonds that hold atoms together. A change in temperature can also do it, as can an electric current.
What chemical changes involve breaking and making chemical bonds?
Breaking of bonds but also formation of new bonds.
Is a chemical bond a physical change?
The formation of chemical bonds is a chemical change.
How does temperature affect physical and chemical chemical change?
A change in temperature can change the rate of physical or chemical change.
What happens to chemical change during a chemical change?
when a chemical change occurs, chemical bonds are broken up

Is chemicals bonding a physical or chemical change?
The formation of chemical bonds is a chemical change.
Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
What happens to chemical bonds during chemical change?
During a chemical change, chemical bonds are broken between atoms in the reactants and new bonds are formed to create products. Energy is either released or absorbed during bond breaking and forming processes. The types and strengths of the bonds determine the overall energy change of the chemical reaction.
How a temperature change is not a chemical change?
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
How can a thermometer be used to help you decide whether your observation is physical or chemical change?
A thermometer can help you decide whether your observation is a physical or chemical change by measuring the temperature change. A physical change typically involves a change in state (solid, liquid, gas) without changing the chemical composition, so the temperature may remain constant. In contrast, a chemical change usually involves the breaking and forming of chemical bonds, which can result in a temperature change.
Is temperature a chemical change?
No, temperature is not a chemical change. Temperature is a measure of the average kinetic energy of particles in a substance and does not involve the rearrangement of atoms or formation of new substances.
