Answer:
134K
Explanation:
Using the ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas constant (0.0821 Latm/Kmol)
T = temperature (K)
Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?
3.25 × 4.738 = 1.4 × 0.0821 × T
15.3985 = 0.11494T
T = 15.3985/0.11494
T = 133.969
Approximately;
T = 134K
Answer:
heat transfer by thermal energy
Explanation:cause thermal is hot air so heat transfer by thermal
Answer:
129.453 kJ is required to heat 0.850 pints of water
Explanation:
1 pint requires 36400 cal of energy to heat a pint of water from room temperature to boil.
Sometimes he uses 0.850 pints. The energy he needs then : 36400 * 0.85 = 30940 cal
Since we know that 1 cal = 4.184 J
⇒ 1 cal = 4.184J so 30940 cal =4.184 * 30940 = 129452.96 J = 129.453 kJ
So 0.850 pints of water require 129.453 kJ, at roomtemperature.
Answer: A dune is a mound of sand formed by the wind, usually along the beach or in a desert. Dunes can also be formed by strong currents beneath the water.
Answer:
Phosphorus cycle
Explanation:
Biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circlated.
There are four types of biogeochemical cycle, they are ; water cycle,carbon cycle,nitrogen cycle and phosphorous cycle
Carbon cycle is the cycle in which photosynthesis and cellular respiration take place.
Water cycle involves transpiration.
Nitrogen cycle Is the cycle that is dependent upon bacteria for nitrogen fixation and denitrification.
Phosphorus cycle is one of the slowest biogeochemical cycle. It does not stay in the atmosphere, because it is normally in a liquid state at room temperature. It does not include the atmosphere.
