<span>Alfred Wegener was the scientist who proposed the Continental Drift Theory in the early twentieth century. Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart.    Thats all i can think f how to answer that, I'm not sure about the theory of plate tectonics, etc.</span>

Ugo [173]

Answer:

-3.617 °C

Explanation:

Step 1: Given data

Mass of water (m): 210.0 g

Energy released in the form of heat (Q): -3178 J (the minus sign corresponds to energy being released)

Specific heat of water (c): 4.184 J/g.°C

Temperature change (ΔT): ?

Step 2: Calculate the temperature change

We will use the following expression.

Q = c × m × ΔT

-3178 J = 4.184 J/g.°C × 210.0 g × ΔT

ΔT = -3.617 °C

How many moles of gas would occupy a 25.0 liter when the temp is 22.0 degrees celsius and the pressure is 646 torr
Luda [366]

Answer:

0.877 mol  

Step-by-step explanation:

We can use the<em> Ideal Gas Law </em>to solve this problem.

pV = nRT     Divide both sides by RT

 n = (pV)/(RT)

Data:

p = 646 torr

V = 25.0 L

R = 0.082 06 L·atm·K⁻¹mol⁻¹

T = 22.0 °C

Calculations:

(a) <em>Convert the pressure to atmospheres </em>

p = 646 torr × (1 atm/760 torr) = 0.8500 atm

(b) <em>Convert the temperature to kelvins </em>

T = (22.0 + 273.15) K = 295.15 K

(c) <em>Calculate the number of moles </em>

n = (0.8500 × 25.0)/(0.082 06 × 295.15)

  = 0.877 mol

Suppose a new liquid were discovered that is identical to water in every way except that it has a lower latent heat of fusion. W
faltersainse [42]

Answer:

It would take less time, because having a lower temperature of latent heat means that at a lower temperature it merges, therefore the closer it will be to the temperature of solification which is 0 degrees Celsius or Celsius ... It is then that it would solidify in less time than water

Explanation:

By acting and having all the same properties as water except for latent heat, it considers that the solidification temperature is 0 degrees Celsius like water.
