Answer:
Temperate Grasslands
Explanation:
Tundras have nothing to do with grass. Tundras are more like ice
Answer:
Condenses at 27.25K.
Freezes at 24.65K.
Explanation:
In order to solve this above question, there is is need to make use of the following equation. The main idea here is to convert degree celsius to Kelvin. Hence,
0°C + 273.15 = 273.15K---------------------(1).
Therefore, we will make use of the above equation (1) and slot in the values for at degree celsius at which it condenses and at degree celsius at which it freezes.
So, we have at temperature at which it condenses:
-245.9°C + 273.15 = 27.25K.
Also, we have at temperature at which it freezes.
-248.5°C + 273.15 = 24.65K.

Answer is: <span>the size of the sample of uranium-238 does not affect its half-life.
</span><span>
The half-life for the
radioactive decay of U-238 is 4.5 billion years and is independent of initial
concentration (size of the sample).
</span>Half-life <span>is
the time required for a quantity (in this example number
of radioactive uranium) to reduce to half its initial
value.</span><span>

<span>Heat
gained or absorbed in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. The heat capacity of aluminum at 25 degrees celsius is 0.9 J/g-C. It is
expressed as follows:</span><span>
Heat = mC(T2-T1)
5800 J = 152000(0.90)(</span>ΔT)
ΔT = 0.42 °C change in temperature
