🔥 Heat and Temperature 🌡️
What is heat ?
It is a form of energy
We cannot see it but we can feel its effects
Sources of heat
Things that
produce heat
are called
heat sources
Heat
from the
Sun
keeps us
warm
Heat can be obtained from burning fuels
Wood
Oil
Petroleum
Coal
natural gas
Electical appliances also give of heat
Difference between heat and temperature
Heat is a form of energy that makes things hot
Temperature is a measurement of how hot something in degrees
The
higher
the
temperature
of an object, the
hotter
it is
Our sense of touch let us know if we are touching something hot or cold but our skin can’t tell the temperature accurately
We use a thermometer to measure temperatures accurately
There are two common types of thermometers are the Clinic thermometer and Laboratory thermometer
Clinic thermometer, used to measure the temperature of the body
Laboratory thermometer, used for measuring the temperatures of objects and substances during science experiments
There are four essential steps to follow order to read the temperature correctly for using a laboratory the
1st : hold the thermometer upright
2nd : look at the level of the liquid in the thermometer
3rd : position your eyes at the same level as the liquid in the thermometer
4th : read the value of the scale nearest to the level as the liquid in the thermometer
How those heat flow ?
Heat
always
flow from a
hotter
to a
colder
place until it reaches the same temperature
What are some effects of heat gain and heat lose in our daily lives ?
A object gains heat, its temperature
A object loses heat, it’s temperature decreases
Matter can expand or become bigger when it gains heat
Matter can contract or become smaller when it loses heat
