The answer is covalent bond
Answer:
117.3 W is being removed.
Explanation:
The heat removed can be calculated as:
Q = m*c*ΔT
Where m is the mass, c is the specific heat and ΔT is the temperature variation. Because there're two components:
Q = mwater*cwater*ΔT + maluminum*caluminum*ΔT
Q = (mwater*cwater + maluminum*caluminum)*ΔT
Searching in a thermodynamic table:
cwater = 4.184 J/g°C
caluminium = 0.9 J/g°C
In 1 minute, the temperature decreases 2.2°C, so ΔT = -2.2°C
Q = (700*4.184 + 300*0.9) * (-2.2)
Q = -7037.36 J
The rate of energy is the potency (P), which is the heat divided by the time. So, for 1 minute (60 s):
P = -7037.36/60
P = -117.3 J/s
P = -117.3 W
The minus signal indicates that the energy is being removed.
Explanation:
(<u>Climate</u>, Weather) is an overall atmospheric condition of a place of 30 years and more while (Climate,<u>Weather</u>) is a condition for a short period of time.
2. (<u>Climate</u>, Weather) is influenced by latitude, altitude, ocean current, and topography.
3. The (<u>higher</u>, lower) the altitude, the (<u>colder</u>, warmer) the climate.
4. (<u>Windward</u>, Leeward) area of the mountain forms precipitation while (Windward,<u>Leeward)</u> gives dry air and warm weather.
5. Ocean currents bring (cold,<u> warm</u>) water and rain from the equator to the poles and (<u>cold</u>, warm) water from the poles toward the equator
Answer:
density=mass/volume
Explanation:
density is defined as mass per unit volume.
Without an external doing work, heat will always flow from a hotter to cooler object. Two objects of different tempatures always interact. There are three different ways for heat to flow from one object to another. They are conduction, convention, and radiation.
