Acetylcholine binds to sarcolemma; sarcolemma then T-tubules depolarize; Ca++ released from terminal cisternae travels along SR, is release into sarcoplasm, then binds to troponin to unblock tropomyosin binding sites allowing cross-bridge formation (i.e., myosin heads bind to actin).
During phase changes, energy is either absorbed or released in the form of heat. This energy is used to break or form intermolecular forces between particles. As a result, temperature remains constant during the phase change until all the substance has transitioned to the new phase.
When water vapor condenses into liquid water, latent heat is released. Similarly, when liquid water freezes into ice, latent heat is also released.
Both a chemical and physical change occurs.
it's because it releases the latent heat of fusion. Latent heat means energy is given out when a substance changes from liquid to solid without a change in temperature. and the transfer of energy doesnt change the KE of the particles, so the temperature remains unchanged. lanten heat gives rise to the change in PE of the particles during the change of state only
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
No, a typhoon is a physical structure energized by the latent heat of phase changes involving water.
During condensation, heat energy is released as water vapor changes to liquid water. This is known as the latent heat of condensation.
The negative value of latent heat in a substance indicates that energy is being released when the substance changes its state, such as from a gas to a liquid or from a liquid to a solid. This release of energy is important because it affects the temperature and behavior of the substance during these phase changes.
The latent heat of condensation.
Energy is absorbed when water changes state from a solid to a liquid to a gas. This energy is used to break the bonds between water molecules during melting and vaporization. It is known as the latent heat of fusion and latent heat of vaporization, respectively.
pChanges in bonding arrangements between atoms and molecules result in absorption or release of heat (called latent heat). For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.
Probably not. A nervous twitch could be a latent fear of the imminent rapture occurring.
Latent energy in a fuel refers to the energy released during the combustion process of the fuel. This energy is stored within the chemical bonds of the fuel and is released in the form of heat when the fuel is burned. It is a crucial factor in determining the energy content and efficiency of a fuel.
When water vapor condenses into liquid water, latent heat is released. Similarly, when liquid water freezes into ice, latent heat is also released. These changes of state involve the release of latent heat because energy is being released as the water molecules transition to a lower energy state.
A thermometer measures temperature by detecting the average kinetic energy of the particles in a substance, rather than the energy involved in phase changes, such as latent heat. Latent heat is the energy absorbed or released during a phase change, like melting or boiling, and does not directly affect the average kinetic energy of the particles that the thermometer detects.
Yes, the temperature of an object remains constant during a change in its state of matter, such as melting or boiling. During these phase changes, energy is absorbed or released as latent heat, which facilitates the transition between states without altering the temperature. Only once the phase change is complete does the temperature begin to change again as heat is added or removed.
The term is "latent heat." It represents the energy absorbed or released by a substance during a phase change, such as when water changes from a liquid to a solid or a gas.
