M1V1 = M2V2

.200 (.025) = 1.60 X 10 -2 (V2)

V2 = .315 L

1.60 x 10-2 M  in 315 mL

3. How many grams of aluminum can be heated from 90°C to 120°C if 500 J of heat energy are applied?
IgorLugansk [536]

<u>We are given:</u>

Initial Temperature = 90°c

Final Temperature = 120°c

Heat applied(ΔH) = 500 Joules

Specific heat(c) = 0.9 Joules / g°C

Mass of Aluminium(m) = ?

<u>Change in temperature:</u>

ΔT = Final temp. - Inital Temp.

ΔT = 120 - 90

ΔT = 30°c

<u>Calculating the mass:</u>

We know the formula:

ΔH = mcΔT

replacing the values:

500 = m(0.9)(30)

500 = m(27)

m = 500/27

m = 18.52 grams

The quartz in granite begins to melt at 650°C, so if we find a migmatite where quartz has melted in a granitic rock and we know
Elanso [62]

Answer:

d. 26.0 km

Explanation:

If the temperature in the region increases with depth by about 25 °C /km, then at a depth of 2 km the temperature would be 50 °C higher, at a depth of 3 km the temperature would be 75 °C higher and so on.

<u>The only way for finding melted quartz would be if the temperature is at least 650 °C.</u>

  • Temperature = 25 °C /km * Depth

We put the data given by the problem and <u>solve for Depth</u>:

  • 650 °C = 25 °C /km * Depth
  • Depth = 26.0 km
