#"10465 J"#

Explanation:

Use this equation

#"Q = mC"Δ"T"#

where

  • #"Q ="# Energy
  • #"m ="# Mass of sample
  • #"C ="# Specific heat of sample (#"4.186 J/g°C"# for water)
  • #"ΔT ="# Change in temperature

#"Q" = 25 cancel"g" × "4.186"/(cancel"g" cancel"°C") × (100 - 0)cancel"°C" = "10465 J"#
