3. A water flask contained 1 l of water. Peter poured out 1/4 l of water to drink. Mrs Tay added 4/5 l of water into the flask.How much water was in the flask in the end?
Jawaban:
There is 1 11/20 l in the flask in the end.
Penjelasan dengan langkah-langkah:
= 1 l - 1/4 l + 4/5 l
= 20/20 l - 5/20 l + 16/20 l
= 31/20 l (improper fraction)
= 1 11/20 l (mixed number)

5. 4950 ml of water is poured equally into 10 bottles. [tex]\frac{3}{10}[/tex] of the bottles of water are used to water the plants. How many milliliters of water is used to water the plants?
Amount of water
=4950ml
Amount of water per bottle
=4950÷10
=495
Water that is for plants
=3/10×495
=148,5 ml
So, the amount of water used is 148.5 milliliters

2. 11365 kj
Penjelasan:
1. diket : m = 10 kg
U = 6,9 x 10 pngkt 4 joule/ kg
jawab : Q = m x U = 10 kg x 69000 j/kg
= 690000 joule
2. diket : m = 5 kg
U = 2.273.000 j/ kg
jawab : Q = m x U = 5 kg x 2.273.000 j/kg
= 11.365.000 joule

16. 6. Evander took out 1 L of water from the refrigerator, when he measured the temperature of the water it showed that the water was at 10 oC. Evander thinks that it is still too cold so he adds 500 g of hot water. The temperature of the new mixture becomes 30 oC. What is the temperature of the hot water? Assume that the specific heat of the water is 4.2 J/g oC. 1 Liter of water equal to 1000 gramstolong bantuin yaa, makasii
Penjelasan:
according to the Black'sLaw:
m1. C. ∆T1 = m2. C. ∆T2
C could be deleted, =>
1000( 30° - 10°) = 500(t - 30°)
1000(20) = 500(t -30)
20000= 500t -15000
20000 +15000= 500t
35000= 500t
t = 35000/500
t = 70°
therefore, the temperature of the hot water
is 70°C

18. Thermal energy required to increase the temperature of 100g water from 20°c to 70°c (specific heat capacity of water is 4200 Joule/kg °C) is
Diketahui:
m = 100 g.
T.Awal = 20°C.
T.Akhir = 70°C.
c = 4200 J/kg°C.
Ditanya:
Q = ?
Jawaban:
21000 J.
Penjelasan:
Pertama-tama konversikan massanya menjadi kg.
m = 100 g = 100 ÷ 1000 = 0,1 kg.
Kemudian carilah kalornya.
Rumus:
Q = m × c × ∆T = 0,1 × 4200 × (70 - 20) =
0,1 × 4200 × 50 = 21000 J.
Semoga Membantu.
