Does hydrogen float or sink in room temperature?
hydrogen floats at room temperature because it has a density less than 1.
How do you measure the temperature in water?
You can measure the temperature of water using a thermometer specifically designed for use in liquids. Place the thermometer in the water and wait for it to stabilize to get an accurate measurement. Submerge the thermometer deep enough to get an accurate reading.
What degree celsius and Fahrenheit are the same?
The temperature where Celsius and Fahrenheit are the same is -40 degrees.
200 degrees Celsius is equal to 392 degrees Fahrenheit.
Do minerals melt and crystallize at different temperatures?
Yes, minerals have varying melting and crystallization temperatures depending on their chemical composition and structure. Each mineral has a unique set of conditions under which it melts or crystallizes, making them useful for determining the temperatures and pressures experienced by rocks during their formation and evolution.
What is the trend for freezing point?
As pressure increases, the freezing point of a substance generally decreases. Conversely, as pressure decreases, the freezing point of a substance generally increases. This relationship is described by the phase diagram of that substance.
What is the speed of sound at 12 degree Celsius?
Speed of sound in air is c ≈ 331 + 0.6 × T.
T = Temperature.
Speed of sound in air at 12 °C is c ≈ 331 + 0.6 × 12 = 338.2 m/s.
What is the temperature change when you heat water from 35 degrees Celsius to 100 degrees Celsius?
Please try to use your brain to solve simple questions such as this one. The change in temperature is simply 100 - 35 = 65 degrees Celsius.
Does steam have definite volume at 105 degrees C?
No, steam does not have a definite volume at 105 degrees Celsius. As a gas, steam will expand to fill its container and take the shape of the container.
One degree Celsius is warmer than one degree Fahrenheit because the Celsius scale has a smaller degree increment than the Fahrenheit scale. Specifically, each degree Celsius is equivalent to 1.8 degrees Fahrenheit.
What is 90.5 degrees Celsius in Fahrenheit?
90.5 degrees Celsius is equal to 194.9 degrees Fahrenheit. You can convert Celsius to Fahrenheit by using the formula: F = (C x 1.8) + 32.
How much is 28 degrees Celsius in Fahrenheit?
28 degrees Celsius is equal to 82.4 degrees Fahrenheit. This conversion can be done using the formula: (Celsius temperature x 9/5) + 32 = Fahrenheit temperature.
What methods do thermometers utilized in measuring temperature?
Thermometers measure temperature using the principle of thermal expansion, where materials physically expand or contract with changes in temperature. Common types include liquid-in-glass thermometers (mercury or alcohol), bimetallic strips, thermocouples, and infrared thermometers, each utilizing different mechanisms to detect and display temperature variations. These methods provide accurate temperature readings by observing the thermal response of their materials to changes in heat.
What is fourth scale for measuring temperature?
the fourth scale for measuring temperature is RANKINE...
What temperature is nuclear reactor?
This is different in different reactor designs:
- boiling water reactors operate at the boiling temperature of water (100C)
- pressurized water reactors operate at over 300C
- several types of very high temperature gas cooled reactors can operate at temperatures up to 1000C
Who has higher melting point Pure or Impure Substance?
A pure substance typically has a higher melting point than an impure substance. Impurities disrupt the regular arrangement of particles in the substance, making it more difficult for them to overcome the intermolecular forces and transition from solid to liquid state. This results in a lower melting point for impure substances.
Is 60celsius equals equals to 32 Fahrenheit?
No, 60 degrees Celsius is equal to 140 degrees Fahrenheit.
What does 225 Fahrenheit equal in Celsius?
225 Fahrenheit is equal to approximately 107 degrees Celsius.
PV/T = PV/T ( forgot who's law that is )
need to convert C to K
30 C = 303.15 K
(725 mmHg)(400 ml)/(303.15 K) = (650 mmHg)(X Vol)/(303.15 K)
197047.5X = 87913500
= 446 ml

What is the state of bromine at 80 degree celsius?
Gas, bromine boils at 59 oC so it would be a gas at 80 oC
The Kelvin temperature scale should be used when expressing Charles's law as a simple direct proportionality because it is an absolute temperature scale where zero represents absolute zero. This allows for the temperature and volume relationship to be directly proportional without any negative values or offsets.
