What is the energy transformation of a thermometer?

As molecules of air move, they hit the walls of a thermometer with kinetic energy. Each collision between an air molecule and the wall of the thermometer results in a transfer of thermal energy from the air to molecules in the thermometer.

How does a thermometer measure body temperature?

Mouth: Place the probe under the tongue and close the mouth. Breathe through the nose. Use the lips to hold the thermometer tightly in place. Leave the thermometer in the mouth for 3 minutes or until the device beeps.

What does a thermometer measure quizlet?

You use a thermometer to measure temperature.

What is the basic principle of thermometer?

A thermometer works on the principle that solids and liquids expand on heating. As the temperature rises, mercury expands causing it to move upwards and depict the temperature.

How does a thermometer relate to the particle theory model?

Show the molecular model animation Heating and Cooling a Thermometer. Point out that when the thermometer is heated, the molecules move faster, get slightly further apart, and move up the tube. When the thermometer is cooled, the molecules move more slowly, get closer together, and move down the tube.

What thermometer is more accurate?

Digital thermometers
Digital thermometers are the most accurate way to measure body temperature. There are many types, including oral, rectal, and forehead, plus many that are multifunctional. Once you decide on the type of thermometer you want, you can think about design, extra features, and price.

What temp means quizlet?

Define Temperature. A measure of the average kinetic energy of the particles in an object.

Is temperature a measure of kinetic energy?

Temperature is a measure of the average kinetic energy of the particles in a substance. It is the kinetic energy of a typical particle.

What are the characteristics of thermometer?

1 Answer

• Thermometer must be sensitive, i.e., a noticeable change in the thermometric property should be observed for a very small change in temperature.
• It has to be accurate.
• It should be easily reproducible.
• It is important that the system attains thermal equilibrium with the thermometer quickly.

What are uses of thermometer?

A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.

Does a thermometer measure kinetic energy?

A thermometer is a glass tube filled with a liquid (mercury) which expands or contracts depending on the temperature of the object it is in contact with. It measures the average kinetic energy (one type of thermal energy) of the molecules of a substance in degrees Fahrenheit (F) or Celsius (C).

Why does liquid in the thermometer rise when?

1. The liquid in the thermometer goes up when the thermometer is heated because heating makes the alcohol molecules of the liquid move faster. The extra speed of the molecules competes with their attraction for one another and causes them to move slightly further apart.

What are the uses of a thermometer?

A thermometer is a tool that measures temperature — how hot or cold something is. Thermometers are used to see if you have a fever or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward.

Does a thermometer measure thermal energy?

Can my iPhone take my temperature?

You can take your temperature using your iPhone by linking the Apple Health app to a smart thermometer. Smart thermometers, like Kinsa’s QuickCare and Smart Ear products, let you upload your health readings to a phone. As long as your iPhone and thermometer are within 10 feet of each other, they can sync automatically.

Does my iPhone have a thermometer?

Does the iPhone Have a Thermometer? The iPhone has temperature sensors within it, but like other smartphones, Apple uses the sensors to monitor the battery and processor’s temperature. In extreme temperatures (hot or cold), these sensors shut down the device to prevent damage.

What are the two types of thermometer?

There are different types, but not all thermometers are right for your child.

• Digital thermometers.
• Ear (or tympanic) thermometers.
• Infared thermometers.
• Strip-type thermometers.
• Mercury thermometers.

What are the different types of thermometer in physics?

Summary

• Three types of thermometers are alcohol, liquid crystal, and infrared radiation (pyrometer).
• The three main temperature scales are Celsius, Fahrenheit, and Kelvin.
• The three phases of water (ice, liquid water, and water vapor) can coexist at a single pressure and temperature known as the triple point.

Why does the production possibilities curve assume full use of factors?

Because an economy’s production possibilities curve assumes the full use of the factors of production available to it, the failure to use some factors results in a level of production that lies inside the production possibilities curve.

What could leave an economy at a point inside its possibilities curve?

Two things could leave an economy operating at a point inside its production possibilities curve. First, the economy might fail to use fully the resources available to it. Second, it might not allocate resources on the basis of comparative advantage.

How does the production curve show production efficiency?

All choices along the curve shows production efficiency of both goods. Production points inside the curve show an economy is not producing at its comparative advantage. Conversely, production outside the curve is not possible as more of both goods cannot be produced given the fixed resources.
