Answer:
layer c
Explanation:
because its furtherest under ground
Answer:
42) 76
b)70
Explanation:
52) because you don't want to confuse different units. one ex)1cm is 1/ 100 of a meter
55) 1 km=1,000 meters
b) 10 decimterers = 1 meter
56)The SI standard for length is the meter the standard for volume is the cubic decimeter
ex) 1cm³=1mL
57) The two scales are the same. but there are no negative temperatures in Kelvin. 0 Kelvin is the lowest temperature possible.
0 Kelvin= -274.5 Celsius
Answer:
T final = 80°C
Explanation:
∴ Q = 18000 cal
∴ m H2O = 300 g
∴ Cp H2O (15°C) = 0.99795 cal/g.K ≅ 1 cal/g.K
∴ T1 = 20°C = 293 K
∴ T2 = ?
⇒ 18000 cal = (300 g)(1 cal/g.K)(T2 - 293 K)
⇒ (18000 cal)/(300 cal/K) = T2 - 293 K
⇒ T2 = 293 K + 60 K
⇒ T2 = 353 K (80°C)
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
