Answer:
A. 0.65g/mL, float
Explanation:
Mass: 325g
Volume: 500mL
D = m/v
D = 325/500
D = 0.65
Therefore, the block has a density of 0.65g/mL and it will float since the density of water is greater than the density of the block.
Hey there !
<span>Convert Joule to KJ :
</span>
1 j ---------------- 0.001 kj
53.69 j ----------- Kj
Kj = 53.69 * 0.001
=> 0.05369 Kj
T = ΔH / <span>ΔS
T = 49.09 / 0.05369
T = 914.32ºC</span>
The scientific method use, and thus going "for, the idea of following the ideal of scientific evidence.
We have to know how urbanization causes pollution.
The reason is: People in urban areas consume more energy, food, and water.
Urbanisation is one of the major problem towards pollution. The smoke from automobiles, factories and power generators make air unhealthy. Also chemical spills and other toxic gases contaminate in air.
The mixing of toxins in the soil is polluting soil which disturbs eco-system.
The high density population in urban area consume more energy , food and water which causes pollution.
