Answer:
115 mL of a gas is at 45.8 kPa and 57.2°C. What is the volume of the gas at 99.3 kPa and 112.3°C?[5] 11. ... What is the pressure of 62.76 g of carbon dioxide (CO2) gas if it occupies a volume of 35,000 mL at standard temperature?
Explanation:
Answer:
kinetic energy
Explanation:
When solids are heated the particles gain energy and start to vibrate faster and faster.
Answer:
The fourth one.
Explanation:
The fourth graph shows an object speeding up ( accelerating ) coz the velocity (tangent at the curve ) at every point is different, hence denoting an acceleration.
It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
Answer:
If each element can be identified by its spectrum then the composition of an unknown star can be determined
Explanation:
The chemical nature of the elements is that they absorb specific wavelength of light depending on their atom. By spectral analysis of the spectrum of emitted light by a body, the body's composition can therefore be determined. As such in order to determine the composition of distant bodies such as planets, stars and other celestial bodies scientists usually make use of spectroscopy.
