Answer:
Explanation:
False.
No. The temperature inside the container is a dependent variable. It depends on what the box is made of.
1.Binary fission
2.simple binary fission
3.transverse binary fission
4.Longitudinal binary fission
5.multiple fission
6.budding
In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere<span> is the uppermost layer, where the atmosphere thins out and merges with interplanetary space. It is located directly above the thermosphere.</span>
Heat_1: Get the ice to 0 degrees
Convert 7 kg to grams
7 kg [1000 grams / 1 kg] = 7000 grams
Heat needed to get the the ice from - 9 to 0
deltat = 0 - -9 = 9 degrees
m = 7000 grams
c = 2.1 joules/gram
Heat_1 = m*c*deltat
Heat_1 = 7000 * 2.1 * 9
Heat_1 = 132,300 joules
Heat_2: Melt the ice.
There is no temperature change. The formula is 333 j/gram
Formula: H = mass * constant
H = 7000 g * 333 J / gram
H = 2331000 joules
Heat_3: Total amount of Joules needed.
2331000 + 132300 = 2 463 300 joules
Convert to Megajoules
2 463 300 joules * 1 megajoule / 1000000 = 2.63 megajoules.
I think it is B) 18 but you'd have to check. Help?
