Answer:
it's a chemical change and an electrolytic reaction
A. ?
b. they have lots of pressure
c. the altitude and pressure
why is everyone saying "Will upvote?"
Pressure since pressure is defined as force per unit area and the molecules exert a force on the walls of the container when they bombard it
Answer: 0.85075J/g.K
Explanation:
Mass of the material = 100g
Energy (Q) = 5104.5J
T1 = 20°C = 293K
T2 = 80°C = 353K
Formula for heat energy (Q) = mc ∇T
Q = mc∇T
∇T = T2 - T1
∇T = 353K - 293K = 60K
Q = mc∇T
C = Q / m∇T
C = (5104.5) / (100 * 60)
C = 0.85075 J/gK
The specific heat capacity of the material is 0.85075J/gK.
Marine food chains at risk of collapse, extensive study of world's oceans finds. ... The acidification of the ocean, where the pH of water drops as it absorbs carbon dioxide, will make it hard for creatures such as coral, oysters and mussels to form the shells and structures that sustain them.
