Answer:
Dia setreoner is free and open source general-purpose diagramming software, developed originally by Alexander Larsson. Dia uses a controlled single document interface.Dia is a diagramming application that can be used to make a large variety of diagrams. Dia is easy to learn and flexible enough to allow power users to create highly customized diagrams.
Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the enzyme lysozyme and the world's first broadly effective antibiotic substance which he named penicillin.
For this discovery he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain.
Answer:
Δ h = 2958.9 kJ/kg
Explanation:
initial state
T₁ = 50⁰C
P₁ = 1 bar
from steam table , Enthalpy at 50⁰C and 1 bar
h₁ = 208.785 kJ/kg
final state
T₂ = 350⁰C
P₂ = 5 bar
from steam table , Enthalpy at 350⁰C and 5 bar
h₂ = 3167.75 kJ/kg
change in entalpy for the process
Δ h = h₂ - h₁
= 3167.75 - 208.785
Δ h = 2958.965 kJ/kg
the change in enthalpy is equal to Δ h = 2958.9 kJ/kg

Answer:
0.053 J/gºC
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 540 g
Heat (Q) = 257 J
Temperature rise (ΔT) = 9 °C
Specific heat capacity (C) =?
The specific heat capacity of mercury can be obtained as illustrated below:
Q = MCΔT
257 = 540 × C × 9
257 = 4860 × C
Divide both side by 4860
C = 257 / 4860
C = 0.053 J/gºC
Therefore, the specific heat capacity of mercury of mercury is 0.053 J/gºC
