The specific heat capacity of water is 4.18 J K⁻¹ g⁻¹. What is the enthalpy (heat) change when 10.00 g of water is heated from 285.0 to 300.0 K (Hint temperature change is the same in °C or Kelvin)?

627j

Explanation:

H=mcΔT

ΔH= 10*4.18*(300-285)

ΔH=10*4.18*15

ΔH=627j

all eukaryotic cell have mitochondria : )

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
