Answer:
An alloy is a mixture of chemical elements, which form an impure substance that retains the characteristics of a metal.
Explanation:
Have a nice day. Auf Wiedersehen.
Answer:
Yes it does contain thermal energy.
Explanation:
Cold objects have SOME thermal energy because the particles of all matter are in constant random motion.
Molar mass of aluminum = 26.982 g/mol.
1 mol of Al = 26.9≈27g = 6.02×10²³ atoms [ avogadro's number]
meaning
1 g | Al = 6.02/27 × 10²³ atoms
so 3.78g | Al = 6.02×3.78]/27 ×10²³
= 0.8428 ×10²³ atoms
= 8.428 ×10²² atoms
Answer:
Friction
Explanation:
Energy is lost to heat as the object overcomes kinetic friction as it slides up the ramp. The energy loss is equal to the work done by the friction force.
The statement 'photosynthesis and cellular respiration are opposite reactions' best describes the relationship between photosynthesis and cellular respiration.
<h3>What is cellular respiration?</h3>
Cellular respiration is a chemical process where foods and oxygen are used to generate ATP in aerobic conditions.
Conversely, photosynthesis is a chemical process where light and carbon dioxide are used to generate chemical energy.
In conclusion, the statement 'photosynthesis and cellular respiration are opposite reactions' best describes the relationship between photosynthesis and cellular respiration.
