Suppose a mercury thermometer shows that the air temperature is 22celcus 72 farenheightdo particles in the air have more average kinetic energy than particles in the mercury?
Yes, particles in the air have more average kinetic energy compared to particles in the mercury. This is because the air temperature is higher than the temperature of the mercury inside the thermometer, so the air particles are moving faster on average.
Do particles in the air have average kinetic energy than particles in the mercury?
It is true.
What do thermometers actually detect about the moving particles that make up a sample of matter?
Thermometers actually detect the temperature of moving particles in motion. Both mercury and alcohol (substances in thermometers) grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold.
What Particles inside of a thermometer temperature goes down?
A very simplified explanation is that at greater temperature, the particles move faster.However, this only applies for one specific substance. When comparing different substances, it would be more accurate to say that (roughly speaking, at least) the temperature is proportional to the average kinetic energy per particle, and per degree of freedom.
Does the particles in mercury have more kinetic energy than the airs kinetic energy?
Im so confused
What a thermometer measures?
A thermometer measures the temperature of an object or environment by detecting the thermal energy present. It typically does so by using either a mercury or digital sensor to provide a numerical readout in degrees Fahrenheit or Celsius.
Why does the liquid mercury in thermometer fall on cooling?
When a thermometer cools, the temperature of the liquid mercury inside it decreases. As the temperature drops, the kinetic energy of the mercury atoms decreases, causing them to move closer together and occupy less volume. This contraction leads to the mercury descending in the narrow tube of the thermometer, reflecting the drop in temperature. Thus, the level of mercury falls as it cools.
Why does temperature in a thermometer go up faster when shaken?
When a thermometer is shaken, the mercury inside it gains kinetic energy, causing its particles to move faster and spread out more. This makes the mercury rise in temperature more quickly as it absorbs heat energy from the surroundings.
How does pressure affect a thermometer?
Heat is transferred thru the glass of the thermometer to or from the liquid (mercury) inside. The heat causes the liquid to either expand (hot) or contract. Since the large bulb end contains most of the liquid, but grass doesn't expand as much as the liquid, the expanding liquid forces itself up (if hot) into the narrow tube, which indicated the temperature. On the molecular level, particles outside the thermometer have a certain kinetic energy (KR) and the particles inside the thermometer also have a certain KE probably a different amount or they are already at the same temperature. Particles (either molecules or atoms) when in either the solid or liquid state, are constantly in motion (for solids, they just vibrate about a fixed, central position. Collision of the particles outside the thermometer and the thermometer itself cause exchange of some KE until the average KE of the outside particles is equal to the average KE of those in the thermometer. When this occurrs they are at the same temp. This change in KE of the particles in the thermometer causes more motion, and this extra motion causes what we call expansion. All molecules in the thermometer are pushing against each other with more force (KE).
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
What is Mercury thermometer use to measure?
A mercury thermometer is used to measure temperature.
