Gasoline use contributes to air pollution
Gasoline is a toxic and highly flammable liquid. The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
Answer:
if you add a neutron to lithium-7 it becomes a compound nucleus of lithium-8
The specific heat capacity of unknown substance is 1.333 g/j/°c
<u><em> calculation</em></u>
Specific heat capacity is calculated using Q= MCΔT formula
where;
Q(heat)= 800 j
M(mass) = 30 g
C(specific heat capacity) =?
ΔT( change in temperature) = 40°c - 20°c = 20°c
make C the subject of the formula by diving both side of the formula by MΔT
C is therefore = Q/MΔT
800j / 30 g x 20°c = 1.333 j/g/°c
D = m / V
1.5 = 78 / V
V = 78 / 1.5
V = 52 mL
Answer:
A. Polar regions receive less solar energy and heat per unit area than tropical regions.
Explanation:
The sun is lower in the sky the farther away from the equator you go (at higher latitudes), so the solar energy is less direct. Climate in areas with less direct solar input tends to be generally cooler.
