Answer:
Q = 813.12 j
Explanation:
Given data:
Mass of lead = 21 g
Initial temperature = 25°C
Final temperature = 327.5°C
Amount of heat absorbed by lead = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 327.5°C - 25°C
ΔT = 302.5°C
Specific heat capacity of lead = 0.128 j/g.°C
Q = m.c. ΔT
Q = 21 g. 0.128 j/g.°C.302.5°C
Q = 813.12 j
Hello,
Question- Which pelagic zone of the ocean exists only in some regions under the open ocean?
Answer- Hello there, your question doesnt make that much sense to me but here is what i can give you.
The (Pelagic zone) Is like the whole ocean and it's columns together. Meaning there is a shallow lighted part and there is also a deep and dark part of the ocean, those all fall under the pelagiz zone. Many creatures live in different parts of the ocean. Deep see animals live in the most deep part of the ocean those animals are called palagic animals. Here is a list in order of all the parts of the palegic zone.
- E p i p e l a g i c (sunlight)
- M e s o p e l a g i c (twilight)
- B a t h y p e l a g i c (midnight)
- A b y s s o p e l a g i c (lower midnight)
- H a d o p e l a g i c.
- Pelagic birds.
- Pelagic fish.
Does that help a little more?
As you can see in my list, those are all the zones in the palagic zone.
