Answer:
C. Graph C
Explanation:
We have a mixture of water and ice.
At 0 °C they are at equilibrium.
water-to-ice rate = ice-to-water rate
Next, we lower the temperature to -3 °C — just slightly below freezing.
The water will slowly turn to ice.
The water-to-ice rate will be slightly faster than the ice-to-water rate.
The purple bar will be slightly higher than the blue bar.
Graph C best represents the relative rates
A. is wrong. The ice-to-water rate is faster, so the water is melting. The temperature is slightly above freezing (say, 3 °C).
B. is wrong. The two rates are equal, so the temperature is 0 °C.
D. is wrong. The water-to-ice rate (freezing) is much greater than the ice-to-water rate, so the temperature is well below freezing( say, -10 °C).
Spring tides is when the daily tidal range is greatest and neap tides are when the daily tidal range is the smallest. As for alignment, spring tides occur when the earth, moon, and sun are directly in alignment with each other. Neap tides occur when the earth is in alignment with the sun, but the moon is at a 90 degree angle from that
Answer:
The answer to your question is: Q = 3153600 Joules
Explanation:
Data
Q = ?
m = 48 kg
T1 = 21°C
T2 = 94°C
Cp = 900 J/g°C
Formula
Q = mCpΔT
Q = (48)(900)(94 - 21) = 3153600 Joules
Answer:
3
Explanation
N is 14, so multiply it by 6 (because 6 moles). Since it's N2, divide it by 2, then divide it by 14 (N in grams).
The barometer would show a decrease in wind speed resulting in the disipation of cloud cover because of the lack of wind, and also because the temperature is dropping there is less precipation because there is no hot air rising to create clouds :)
