What is the viscosity of liquid butane?

The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium….Chemical, physical and thermal properties of n-Butane.

What is the heat of vaporization of acetone?

The heat of vaporization of acetone, CH_3COCH_3, at its boiling point is 29.1 kJ/mol.

### How cold is liquid butane?

Butane has a freezing point of -216.4 °F (-138 degrees °C), meaning it will not freeze under usual cold conditions.

### Can propane become a solid?

Propane is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid (or a solid at very cold conditions).

Does propane turn into solid?

Propane is a colorless, odorless gas. At normal pressure it liquifies below its boiling point at −42 °C and solidifies below its melting point at −187.7 °C.

What temp is liquid butane?

Gas BP °C As LPG
propane – 42 14 atm 38°C liquid
butane – 0.5 2.6 atm 38°C liquid

#### How do you calculate heat of vaporization?

Use the formula q = m·ΔHv in which q = heat energy, m = mass, and ΔHv = heat of vaporization.

#### Does acetone evaporate at room temperature?

why do we have two heat it to its boiling point? At room temperature the rate of evaporation of acetone is slow, to speed up the process to evaporate all the acetone in the mixture, we supply heat.

Can you put a can of butane in the freezer?

Cans of butane are not likely going to freeze unless they are in controlled environments to achieve their freezing point. Although butane won’t freeze from the weather, it is sensitive to cold conditions. Locations that commonly experience sub-freezing winter temperatures may be dangerous to butane.

Is there a manual for the genius™ checker/calibrator?

This manual supersedes previous versions of the manual and Troubleshooting Guide document DC00105052. This manual describes the operation of the Genius™ Checker/Calibrator. This device has been developed to check the accuracy of the Genius™ 3 Tympanic Thermometer and automatically recalibrate the thermometer.

## How many Genius™ disposable probe covers do I Need?

1. Genius™ Checker/Calibrator 2. Power module with AC adapter 3. Probe cable 4. Operator’s Manual 5. Genius™ 3 Thermometers to be tested 6. 8 Genius™ Disposable Probe Covers, part 303030. For calibration check only, 2 probe covers are required. If recalibration is required, 6 additional probe covers are needed.

## Does the genius™ checker/ calibrator support a genius™ 2 tympanic thermometer?

In addition to supporting the Genius™ 3 Tympanic Thermometer, the Genius™ Checker/ Calibrator also fully supports the Genius™ 2 Tympanic Thermometer. Throughout this document, where a Genius™ 3 Thermometer is noted, the caution, warning or instruction also applies to a Genius™ 2 Thermometer unless otherwise noted.

How long does it take to insert the Genius™ 3 thermometer?

Refer servicing to qualified service personnel. • When prompted to insert the Genius™ 3 Thermometer into one of the blackbody targets, there is a 60 second window of time to accomplish the insertion. If the time delay exceeds this period, the procedure will be terminated.
