PPT-Heat and Temperature PES 1000 – Physics in Everyday Life

How do we measure Temperature Thermal expansion The fluid in a thermometers 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. • •hen applying pes�cides, other than RUPs, to property owned by you or your employer.• Applica�ons of general use pes�cides by public employee Presented by: N.S Thomas.

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. . Scales of Measurement. Celsius scale – based on where water freezes (0. . C) and where water boils (100. . C). Kelvin scale – based on the movement of particles. . Absolute Zero. At 0 K, all particle movement has ceased. Developing A Deeper Discipleship . Everyday Discipleship. “If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow me” (. Lk. . 9:23).. A disciple is not above his teacher, nor a servant above his master. It is enough for a disciple that he be like his teacher, and a servant like his master…” (Mt. 10:24, 25a).. 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).. Fins and Extended Surfaces. 1.

Morski psov je več kot 350 vrst, razširjeni pa so domala v vseh morjih sveta, nekatere vrste npr. morski bik pa so sposobne celo življenja v sladki vodi. . Morski psi so še starejši od dinozavrov, saj obstajajo že več kot 400 milijonov let, v vseh teh letih pa niso doživeli veliko sprememb. .
