Answer:
Twice a month, sun and earth are perpendicular
Explanation:
Answer:
The specific heat capacity of a metal is 1.31 J/g°C = C
Explanation:
A classical excersise of calorimetry to apply this formula:
Q = m . C . ΔT
177.5 J = 15 g . C (34°C - 25°C)
177.5 J = 15g . 9°C . C
177.5 J /15g . 9°C = C
1.31 J/g°C = C
The arrow that represents the transition in which dew is formed would be arrow 4.
<h3>How is dew formed?</h3>
Dew is formed by condensation. Condensation, in itself, involves a transition from a gas phase to a liquid phase.
From the diagram, the arrow that represents a transition from gas to liquid is arrow 4.
Thus, the arrow that represents the transition that leads to the formation of dew would be arrow 4.

Answer:Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
