#"2133.84 kJ"#

Explanation:

Use this equation

#"Q = mC"Δ"T"#

where

  • #"Q ="# Heat
  • #"m ="# Mass of sample
  • #"C ="# Specific heat of sample (#"4.184 kJ/kg°C"# for water)
  • #"ΔT ="# Change in temperature

#"Q" = 30 cancel"kg" × "4.184 kJ"/(cancel"kg" cancel"°C") × (37 - 20) cancel"°C" = "2133.84 kJ"#
