EXPOSURE
Contact
You can be exposed to a hazardous material by:inhalation - breathing it in so it can damage the lungs or be passed to the blood for circulation through the bodyingestion - swallowing itskin contact - coming in direct contact with something that damages the skinskin absorption - coming in contact with something that does not damage the skin but moves through it and is then circulated through the body to sites where it can cause damageinjection - having it inserted into the muscle or blood through a needle or a cut or other damage to the skin
When iodine comes into contact with starch, a chemical reaction occurs that results in the formation of a dark blue or black color. This reaction is used as a test to detect the presence of starch in a substance.
Conduction is the transferring of heat from one substance to another. Therefore, conduction usually occurs when one hot object comes into contact with another object that is not as hot.
Conduction is the process that describes the transfer of heat directly by contact. It occurs through the collision of molecules within a substance or between two substances in contact.
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
Conduction is the transfer of energy from one substance to another through direct contact. This transfer occurs as particles collide and transfer kinetic energy to each other, leading to an overall flow of heat.
A contact exposure would typically be in your system immediately after contact occurs. The duration it remains in your system can vary depending on the type of contact and the substance involved. It's important to wash the affected area thoroughly after contact to minimize any potential absorption into the body.
Chemical Change
The transfer of heat by the particles in a substance is known as conduction. In conduction, heat is passed from one particle to another through direct contact. This process occurs in solids, where particles are closely packed together.

Conduction is the transfer of heat energy through direct contact between particles in a substance. It occurs when particles collide and transfer their kinetic energy to neighboring particles, leading to an overall transfer of heat through the substance. Materials that are good conductors, such as metals, allow heat to move through them quickly.
