What is an expression of Avogadro's law (k constant)?
Equa; amounts of all gasses have the same volume at the same conditions
The specific heat of substance A is greater than that for substance B If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these s?
The specific heat of substance A is greater than that for substance B. If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these samples, substance A will have a lower temperature than substance B.
Is there always water in the air?
Yes, there is always some amount of water vapor in the air, even in seemingly dry conditions. This humidity can vary significantly depending on factors like temperature and location. While the concentration of water vapor can be low in arid regions, it never reaches zero, as the atmosphere constantly holds moisture in varying amounts.
Why do particles have different amounts of kinetic energy?
Because they have different temperatures and when you measure an object's temperature, you measure the average kinetic energy of all the particles in the object.
How would you explain testing how two types of soap work using control and variable?
The control is what you're washing, amount of dirt, kind of dirt, temperature of water. The kind and amount of soap are variables, although when using the same kind in different amounts, the kind is control. The temperature of water is also control and variable depending on the test.
What equal volumes of gases under the same conditions of temperature and pressure have equal?
Equal volumes of gases under the same conditions of temperature and pressure have an equal number of molecules, according to Avogadro's Law. This relationship allows for direct comparisons of the amounts of different gases.
Why does the density of a substance remain the same for difference amounts of the substance?
Yes, under the same physical conditions influencing volume that is true (e.g. temperature and pressure).
What would be a direct effect of increases of the amounts of this gas?
Increasing the amount of a gas increases the temperature and pressure in a container
What would be a direct effect of increase in the amounts of gas?
Increasing the amount of a gas increases the temperature and pressure in a container
What would be a direct effect of increase in the amounts of this gas?
Increasing the amount of a gas increases the temperature and pressure in a container
Which of the three variables that apply to equal amounts of gases are directly proportional Which are inversely proportional?
The following variables are directly proportional: Temperature and Pressure Temperature and Volume These variables are inversely proportional: Pressure and Volume
What harmful gases are in Jupiter?
Jupiter's atmosphere is mostly composed of hydrogen and helium, with small amounts of methane and ammonia. Harmful gases such as sulfur compounds and hydrocarbons may also be present, but in trace amounts. The extreme conditions on Jupiter, including high temperature and pressure, make it inhospitable for human life.
When a star forms where is the build up of temperature and pressure the greatest?
The build up of temperature and pressure is greatest at the core of the forming star. This is where gravity causes atoms to be squeezed together and nuclear fusion reactions begin, releasing huge amounts of energy.
Why do diamonds form in the mantle?
Diamonds form in the Earth's mantle due to the combination of high pressure and high temperature conditions that exist at significant depths within the planet. Under these extreme conditions, carbon atoms can crystallize and bond together to form diamond structures over long periods of time.
Nuclear fusion takes place in the Sun's?
core, where hydrogen atoms are fused to form helium atoms under immense pressure and temperature conditions. This process releases large amounts of energy in the form of light and heat, powering the Sun and enabling life on Earth.
Why don't hurricains occur in the south Atlantic Ocean?
Hurricanes are caused by an extreme difference in atmospheric pressure. They are created by a difference in the air pressure from the centre, the eye, to the extreme edge, where the winds are highest. They are a product of high temperature, in the tropical regions,with massive amounts of water laden air rising, caused by the rotation of the earth. Therefore these conditions are not evident in areas of temperate ocean....
Why is pressure required to kill endospores in an autoclave?
Pressure increases the boiling point of water, when it does boil the steam is now 'super-heated'. It is at a higher temperature than the boiling point of 100C (usually 121C and 15psi for an autoclave) this quickly transfers much greater amounts of heat energy to the object being autoclaved. The vast majority of microorganisms and even pathogenic bacterial spores cannot withstand this temperature and pressure for long, the lipids and proteins in their cell walls and membranes disintegrate and they are killed.
