Answer:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Explanation:
Answer:
To find volume you can either look at the displacement of the water or Length•Width•Height
Explanation:
11) 12
12) 340 mL
13) 196 m\
Here we have to get the item which has more thermal energy among the given options.
The item a) will have more thermal energy than b)
The thermal energy of a compound can be determined from the formula H = m×s×t (H = thermal energy, m = mass of the compound, s = specific heat of the compound, t = temperature)
a) Here m = 500 g, s = 1 g/mL and t = 50⁰C (as the density of water is 1 g/mL thus its volume is equivalent to its mass)
Thus the thermal energy H = 500 × 1 × 50 = 25000 Cal (The energy needed to raise 1⁰C temperature of 1g water is calorie unit)
similarly,
b) Here m = 100 g, s = 1 g/mL and t = 50⁰C (as the density of water is 1 g/mL thus its volume is equivalent to its mass)
Thus the thermal energy H = 100 × 1 × 50 = 5000 Cal (The energy needed to raise 1⁰C temperature of 1g water is calorie unit).
Thus option a) i.e. 500 mL of water at 50 degree Celsius will have more thermal energy.
Thus the thermal energy of both the item have calculated and compared.
Everything will be the same except that the atoms will be together nothing changes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
Answer:
Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, overconsumption, overexploitation, pollution, and deforestation, to name but a few.
