Thermometer Flashcards
The ——— can measure temperature because the substance of the liquid inside always expands (increases) or contracts (decreases) by a certain amount due to a change in temperature
thermometer
The thermometer can measure temperature because the substance of the liquid inside always expands (increases) or contracts (decreases) by a certain amount due to a
change in temperature
is an instrument for measuring temperature.
Thermometer
Most thermometer consist of a thin tube filled with either a —— or.
liquid mercury
alcohol
As the liquid in a thermometer gets warmer, it —— and —— in the tube.
expands
rises
As the liquid gets cooler, the liquid —— and —— in the tube.
contracts
drops
A —- contains alcohol.
household thermometer
An alcohol thermometer can measure a lower temperature of —- to an upper limit of
115°C
78°C
An ——— can measure a lower temperature of 115°C to an upper limit of 78°C
It is cheaper and safer than mercury.
alcohol thermometer
=can only measure temperature within a range of -39°C to 357°C.
MERCURY THERMOMETER
is a toxic and are now phased out in the market.
Mercury thermometer
Water is not used in thermometers because of its
abnormal expansion.
is not used in thermometers because of its abnormal expansion.
Water
is used to measure the temperature in the metric system.
Celsius scale
The unit of temperature on the Celsius scale is degree Celsius (°C).
Water freezes at —— and boils at.
0 °C
100 °C
Is another metric temperature scale often used by scientist.
Kelvin scale
The —— is preferred by scientists in solving gas law problems because of 0 K (absolute zero) means that the kinetic energy of the particles is zero.
Kelvin scale
Another temperature scale used today.
FAHRENHEIT SCALE
In this scale, the freezing point of water is 32°F and the boiling point of water is 212 °F.
FAHRENHEIT SCALE
In this scale( °F), the freezing point of water is —— and the boiling point of water is ——
32 °F
212 °F.
=This scale is commonly used in the US.
FAHRENHEIT SCALE
The first recorded thermometer was produced by
Italian scientist during the
sixteenth century.
Mercury thermometer can only measure temperature within a range of —- to —-.
-39°C
357°C
