What conditions might cause a
scientist to modify
or revise a
hypothesis
Answer:
Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

At stp,250cm3 of gas had a mass of 0.36g.what result does this give for the molar mass of the gas
Answer:
32,256g/mol
Explanation:
n= V/Vm
n = 0.25/22.4
n = 0.01
0.01 = 0.36/M
M = 0.36/0.01
do all types of energy have the same amount of energy
Answer:
Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on earth possible. Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth.

En la tienda compre una botella con agua la cual no venía etiquetada, ¿Que unidades de medición debe contener la etiqueta para saber la masa de la botella, su volumen y a qué temperatura debe mantenerse?
La unidad de medición para saber la masa de la botella es el gramo.
La unidad de medición para saber el volumen de la botella es el centímetro cúbico o el mililitro o el litro.
La unidad de medición para saber la temperatura de la botella es el grado Celsius.
Inicialmente, vamos a asumir que la botella de agua ha sido comprada en una zona donde las unidades del Sistema Internacional de Medidas es el Sistema Estándar de Pesas y Medidas. En este problema, se requiere conocer tres unidades para la Masa, el Volumen y la Temperatura, cuyas Unidades Fundamentales son las siguientes:
Masa - Kilogramo ([tex]kg[/tex])Volumen - Metro cúbico ([tex]m^{3}[/tex])Temperatura - Grado Celsius ([tex]^{\circ}\,C[/tex])Puesto que la adquisición de botellas de agua en almacenes se realiza en forma Minorista, tanto el Volumen como la Masa, Propiedades Extensivas de la Materia, deben basarse en Unidades Derivadas, es decir, Unidades relacionadas con Unidades Fundamentales mediante relación constante, mientras la Temperatura debe ser una Unidad Fundamental por ser una Propiedad Intensiva de la Materia. Las Unidades más usuales para la botella de agua son:
Masa - Gramo ([tex]g[/tex])Volumen - Centímetros Cúbicos ([tex]cm^{3}[/tex]) o Mililitros ([tex]mL[/tex]) o Litros (L)Temperatura - Grado Celsius ([tex]^{\circ}\,C[/tex])La unidad de medición para saber la masa de la botella es el gramo.
La unidad de medición para saber el volumen de la botella es el centímetro cúbico o el mililitro o el litro.
La unidad de medición para saber la temperatura de la botella es el grado Celsius.

The volume (V) of an enclosed mass of gas is 350kPa. The pressure of the endlosed gas is now decreased to 125kPa, at constant temperature. What will the new volume of the gas be, in terms of V (2)
Answer: V1/V2 = 0.357,
V2 = (V1/0.357) or 28.0*V2
Explanation: Use the combined gas law: P1V1/T1 = P2V2/T2 We want to find V1/2 (or V2/V1). Rearrange:
V1/V2 = (P2/P1)(T1/T2)
The units all cancel. Temerature is constant, so (T1/T2) = 1.
V1/V2 = (125/350)*(1)
V1/V2 = 0.357
What is the formula mass of a compound with 2 aluminum atoms and 3 oxygen atoms?
Answer:
[tex]\boxed {\boxed {\sf 101.96 \ amu}}[/tex]
Explanation:
Formula mass is the sum of the atomic masses of the atoms in a molecule. Essentially, it is the mass of 1 molecule of a compound.
We are given a compound containing 2 aluminum atoms and 3 oxygen atoms. We will use the Periodic Table to look up the atomic masses of the 2 elements in the compound.
Al: 26.981538 amuO: 15.999 amuThese are the atomic masses of 1 atom of the element. Remember we have 2 Al atoms and 3 O atoms. We multiply the element's atomic mass by the number of atoms of that element in the compound.
2 Al: 26.981538 amu *2= 53.963076 amu 3 O: 15.999 amu * 3=47.997 amuNow we add the atomic mass of 2 Al atoms and 3 O atoms.
53.963076 amu + 47.997 amu = 101.960076 amuWe may want to round this answer to the hundredth place. The 0 in the thousandth place tells us to leave the 6 in the hundredth place.
101.96 amuThe formula mass of a compound with 2 aluminum atoms and 3 oxygen atoms is approximately 101.96 atomic mass units.

When a metal such as copper is heated,it expands. Can anyone tell me what happens to the metal particles as the solid metal expands?
Answer:
The metal molecules inside start to vibrate faster, causing the solid to change to liquid if exposed to the intense temperature over a long period of time.
Explanation:
As my answer states, but for an explanation, lets say you are boiling an ice cube, it will start to turn into liquid water, that is because it has been exposed to that heat for a long period of time. The same will happen for the metal, if its exposed for long enough, it will turn into a liquid, then can be turned into a gas because the molecules are vibrating so quickly that they start to easily move apart.
Hope this helps, let me know if any more clarification is needed.
