Jawaban:

602.500 J

Penjelasan:

Diketahui :

– m = 1000 g

= 1 kg

– c es = 2.100 J / kg°C

– c air = 4.200 J / kg°C

– L es = 340.000 J / kg

– T1 = -5 °C

– T2 = 0 °C

– T3 = 60 °C

Ditanya :

Q total?

Jawaban :

(–) Cari Q1

Q1 = m . c es . ( T2 – T1 )

= 1 . 2.100 ( 0 – ( -5))

= 10.500 J

(–) Cari Q2

Q2 = m . L es

= 1 . 340.000

= 340.000 J

(–) Cari Q3

Q3 = m . c air . ( T3 – T2 )

= 1 . 4.200 ( 60 – 0 )

= 252.000 J

(–) Cari Q total

Q total = Q1 + Q2 + Q3

= 10.500 + 340.000 + 252.000

= 602.500 J
