How does the movement of particles of matter change when temperature increases?
saveliy_v [14]

Answer:

Increases

Explanation:

The movement of particles of the matter increases with the increase in temperature.

The particles gain kinetic energy with increasing temperature and move in faster rate.

<u>For example:</u> When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.

Hence, the correct answer is "increases".

Fault trees are an approach to hazard analysis that, for each identified hazard, break down that hazard to find how that hazard
Alexus [3.1K]

Hazards are placed at the root of the tree and determining the cause of the hazard is the correct option for the following hazard analysis questions.

Fault Tree Analysis (FTA) explores how selected “top” faults (abnormal conditions) or fault events such as accidental/unwanted releases of hazardous materials can be resolved to their causes. Hazard analysis is defined as the process of gathering and interpreting information about the hazards and conditions leading to their existence in order to determine what is food safety related and must be addressed in the HACCP plan. Hazard analysis is used as the first step in the risk assessment process. The result of hazard analysis is the identification of different types of hazards. A hazard is a potential condition that may or may not exist.
