What is thermistor diode?
A semiconductor device that is particularly sensitive to changes in temperature, permitting it to serve as an accurate measure of temperature.
How the resistance value for the linear resistance can be changed?
Resistance can be changed by strain over time and changes in the temperature. Resistance thermometers are sensors that are used to measure temperature by correlating the resistance of the RTD elements.
What does a thermistor do that makes it different from a thermocouple?
a thermistor is a temperature sensitive resistor - to measure temperature you must measure its resistance and convert that resistance to equivalent temperaturea thermocouple is a temperature sensitive voltage source(i.e. battery) - to measure temperature you must measure the voltage across it and a reference thermocouple at a known constant temperature connected in series with it and convert that voltage to equivalent temperatureNote: Thermistors do not require reference thermistors, thermocouples do require reference thermocouples at a known constant temperature. Thermocouples are more linear than thermistors, making them easier to read accurately. Thermocouples are available that are far more sensitive to small changes in temperature than thermistors.
Why can a semiconductor measure temperature?
Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
What voltage does a Resistor temperature detector put out?
None. An RTD is a passive device. It changes resistance as the temp varies. Your circuit must basically measure the resistance to determine temp. There are many different types of RTD's, each with it's own temperature curve.
How can I make a simple calorimeter?
To make a simple calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and a heat source to generate heat. Place the container with water on the heat source and measure the initial temperature. Apply heat to the water and record the temperature change. By measuring the amount of heat applied and the temperature change, you can calculate the heat capacity of the calorimeter.
Explain the function of each part of a calorimeter?
here are the parts, idk the functions tbh. e2020 doesnt really look that close at the homework answers, now does it ;) im on to you... oxygen supply ignition wires stirrer insulating jacket bucket heater water ignition coil steel bomb sample crucible air space magnifying eyepiece thermometer
How can I build a simple calorimeter?
To build a simple calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and a heat source to generate heat. Place the heat source under the container, measure the initial temperature of the water, and then record the temperature change as the heat source warms the water. This will help you calculate the amount of heat energy released by the heat source.
How do you test to see if a container is hot?
To test if a container is hot, you can cautiously place the back of your hand near but not touching the surface for a few seconds. Another method is to use a thermometer to measure the temperature of the container. Additionally, you can use a heat-sensitive sticker that changes color at certain temperatures to determine if the container is hot.
What is the measure of how a transistor reacts to changes in temperature?
The thermal voltage.
What is the dependent variable in an experiment that shows how the volum of gas changes with changes in temperature?
VolumeThe independent variable is the one you determine, and the dependent variable is the one you measure. In this case, you choose the temperature, and measure the volume.
How could a student test the effect of removing heat from a gas that is stored in a sealed container?
The student could measure the temperature and pressure of the gas in the sealed container before and after removing heat. By tracking changes in temperature and pressure, the student can observe how cooling the gas affects its properties, such as volume and pressure. This can help demonstrate the relationship between temperature, pressure, and volume in a gas.
Is the temperature of a gas a measure of how hard its molecules hit the walls of its container?
Yes, the temperature of a gas is a measure of the average kinetic energy of its molecules. This kinetic energy is related to the speed at which the gas molecules move, which in turn affects how hard they hit the walls of the container.
What does a thermister do and how does it function in a circuit?
A thermistor is a type of resistor that changes its resistance with temperature. In a circuit, a thermistor is used to measure temperature by detecting the change in its resistance. When the temperature changes, the resistance of the thermistor changes, which can be measured and used to determine the temperature in the circuit.
How can one build a calorimeter?
To build a calorimeter, one can use materials such as a insulated container, a thermometer, a stirrer, and a known heat source. The calorimeter is used to measure the heat released or absorbed during a chemical reaction. By carefully constructing and calibrating the calorimeter, one can accurately determine the heat changes in a system.
How is heat measured in a calorimeter?
Heat is measured in a calorimeter by monitoring the temperature change that occurs when a substance undergoes a chemical reaction or physical process within the calorimeter. This change in temperature is used to calculate the heat transfer associated with the reaction or process.
What is thermistor diode?
A semiconductor device that is particularly sensitive to changes in temperature, permitting it to serve as an accurate measure of temperature.
