PPT-Heat and temperature

Unit 2 What is matter Matter is what makes up all substances whether it is a solid liquid or gas Molecules atoms and subatomic particles are all matter Whats matter made of. Temperature. Most materials expand when heated. Liquid thermometers based on mercury or alcohol expansion are common. Temperature is related to the random motion of atoms and molecules in a substance. . Heat Energy. Heat energy is due to the movement of atoms or molecules.. As atoms move faster they create more energy = causing Heat!. Thermal Energy. Depends upon the mass, temperature and phase of an object.. On the front counter there is a perpetually thirsty bird. Do NOT touch him.. Write down all your . observations. of the motion. Do not try to explain why it’s happening—just look at WHAT is happening. . Introduction to Heat. Heat is a form of energy.. A large amount of energy ends up as heat.. Example: in a car some of the chemical energy stored in petrol is turned into heat energy. . Heat can have a significant effect on solids, liquids and gases (such as expansion).. 2.1. Temperature and the . Zeroth. Law of Thermodynamics. 2.2. Thermal Expansion. 2.3. Heat and the Absorption of Heat by Solids and Liquids. 2.4. Work and Heat in Thermodynamic Processes. 2.5.

Thermal expansion . – The fluid in a thermometer’s bulb heats up and expands, increasing the volume until it flows up the tube of the thermometer.. Color change. – Some materials change color based on their temperature. Examples are forehead thermometers and mood rings.. Discovery Education Video:.

TRIAGE History, or axillary using mercury thermometer), BP, Pulse, Respiratory Rate, Oxygen Saturation and mental status using AVPU ** 1. Assess and manage airway , breathing and circulation Defining Temperature. Temperature: a measure of the average kinetic energy of the particles in a substance. Adding or removing energy usually changes temperature. Internal Energy: energies associated with atomic motion.
