Lesson 1 Word temperature Fahrenheit scale Celsius scale Kelvin scale absolute zero Definition the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch of or denoting a scale of temperature on which water freezes at 32° and boils at 212° under standard conditions. of or denoting a scale of temperature in which water freezes at 0° and boils at 100° under standard conditions. Picture Sentence The Fahrenheit scale is used in the USA mostly The Celsius scale is used in Europe and other places. the SI base unit of thermodynamic temperature, equal in magnitude to the degree Celsius. The Kelvin scale is used by scientists the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to –273.15°C or –459.67°F. Absolute zero is so cold it would stop every molecule in its object 1
heat make or become hot or warm. Lesson 2 Word convection convection current radiation conduction ​Lesson 3 Word Definition Picture Sentence Picture Sentence the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat. a current in a fluid that results from convection the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. Definition
conductor a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this. insulator a substance that does not readily allow the passage of heat or sound. specific heat the heat required to raise the temperature of the unit mass of a given substance by a given amount thermal expansion tendency of matter to change in shape, area, and volume in response to a change in temperature. Water has an specific heat capacity of 4181
