Heat capacity of aluminium = 0.900 J/g°C
While heat capacity of water = 4.186 J/g°C
Heat = heat gained by water + heat gained by aluminium
Heat gained by water = 100 × 4.186 × 30.5
= 12767.3 Joules
Heat gained by aluminium = 15 × 0.9 × 30.5
= 411.75 Joules
Heat required = 13179.05 Joules or 13.179 kJoules
Answer:
What is the volume of the balloon when it rises in the atmosphere to a place where pressure is 640mmHg
Answer:
They are produced from rocks (parent material) through the processes of weathering and natural erosion.
Explanation:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
<span>Gamma radiation has a shorter wavelength, a higher frequency and higher energy than radio radiation.
Wavelength is inverse to frequency and energy (i.e. higher wavelength means lower frequency and lower energy, and vice versa).</span>
1. they work ways faster
2. you don't need 100 people making the same thing at once
3. its a better chance of not getting an injury
