Answer:The purpose of rice paddies is to grow rice in dry areas or areas that don't get that much rain. Also, they are used by using flooded water to grow.
Explanation:
Answer:
Q = 44.9 j
Explanation:
Mass of iron = 5.0 g
Change in temperature = 20 °C
Specific heat of iron = 0.449 j/g.°C
Heat transferred = ?
Formula:
<em>Q = m.c. ΔT
</em>
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Solution:
<em>Q = m.c. ΔT
</em>
Q = 5 g × 0.449 j/g.°C × 20 °C
Q = 44.9 j
Platinum plus chlorine equals 0.889 grams whereas the platinum alone is 0.509grams so 0.509/0.889grams = 57% of the mass of the platinum plus chlorine. The chlorine would be 0.889-0.509=0.38 grams. The chlorine would make up about 42.7% of the total mass in grams.
