Someone pls help with question 4

given.. mass of copper 2kg

from the concept

heat lost from an object=heat gained by the other object

Heat=McΔT

Mč x Cč x ΔTč = Mw x Cw x ΔTw

2kg x 385J/kg°C x (100°c - {F}) = 5kg x 4200J/kg°C x ({f} - 20°C)

77000 - 770F = 21000F - 420,000

21770F =497000

divide both sides

F=22.83°C

therefore the final temperature of the water was 22.83°C

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^

if you answer my question i will answer yours
