The_____ temperature__difference between the ice cubes and the water causes _____heat__ energy to be transferred from the water to the ice cubes.

Explanation:

When you put ice cubes in water, the ice cubes will slowly melt and also become water. This occurs because the water has  higher temperatures than the ice cubes. Heat energy, therefore, is transferred from the water to the ice making the ice cubes melt.

Remember  the law of thermodynamics of entropy- the entropy of a system is always, spontaneously, on the increase.  Because the two systems (ice cubes and water) are connected and can share energy and matter, this exchange happened until both systems are in equilibrium (in this case until temperatures and water molecules are the same all across).

Answer:

iron = 15000 kg 95% sulfuric acid = 27646.32 kg

Explanation:

The molar volume to a gas is 22.4 L, which means that a mole of a given gas at 0°C and 1 atm will have a volume os 22.4 L.

1 m3 - 1000 L

4870 m3 - x

x = 4870 * 1000 = 4.87 *10^6 L

1 mole - 22.4 L

y mole - 4.87 * 10^6 L

y = \frac{4.87 * 10^6}{22.4} = 2,17 *10^5 moles (if 100% of the H2 is used)

as 20% of it is lost, we need to know how much more we need to use.

80% - 2.17 * 10^5 moles

100% - z

z = \frac{2.17* 10^7}{80} = 2,68*10^5 moles

so we would need 2.68*10^5 moles of iron and sulfuric acid.

1 mole of iron - 56 *10^-3 kg

2.68*10^5 moles - t

t= 2.68*56 *10^2 = 15000 kg

1 mole of sulfuric acid - 98 * 10^-3 kg

2.68*10^5 - u

u = 2.68*98 *10^2 = 26264 kg (if 100%)

95% - 26264 kg

100% - v

v = \frac{26264 * 100}{95} = 27646.32 kg

which atoms are moving faster those in a spoon at 0 degrees fahrenheit or those in a fork 0 degrees celsius
myrzilka [38]
I would say the atoms in the fork are moving faster. 0 degrees Fahrenheit is -17.7778 in Celsius while 0 degrees in Celsius is equal to 32 degrees in Fahrenheit.
