Answer:
pretty sure it's C,
Explanation:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. ... This hot added material cools down by conduction and convection of heat.
Ferns reproduce with spores which existed the longest in Earth history.
Gymnosperms reproduce with cones and has needle-like, waxy leaves.
Angiosperms reproduce with flowers and newest type of plant in Earth history.
<h3>How ferns, gymnosperm and angiosperm reproduce?</h3>
Ferns reproduce with spores that existed the longest in Earth, gymnosperms reproduce through the formation of cones having needle-like, waxy leaves whereas angiosperms reproduce with flowers which turns into seed. The newest type of plant in Earth history is also belongs to this group.

Erosols aren't aerosols at all. No, really, let's be clear about this. An aerosol is really the cloud<span> of </span>liquid and gas<span>that comes out of an aerosol can, not the can itself. In fact, to be strictly correct about it, an aerosol is a fine mist of liquid, or lots of solid particles, widely and evenly dispersed throughout a gas. So clouds, fog, and steam from your kettle are all examples of aerosols, because they're made up of </span>water<span> droplets dispersed through a much bigger volume of air. Smoke is an aerosol too, though unlike those other examples (which are liquids dispersed in gases) it's made up of </span>solid<span> particles of unburned carbon mixed through a cloud of warm, rising air. Even </span>candles<span> make aerosols: the smoky steam swirling above a candle flame consists of soot and water vapor dispersed through hot air.

Answer:
c = 4016.64 j/g.°C
Explanation:
Given data:
Mass of substance = 2.50 g
Calories release = 12 cal (12 ×4184 = 50208 j)
Initial temperature = 25°C
Final temperature = 20°C
Specific heat of substance = ?
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Solution:
Q = m.c. ΔT
ΔT = T2 - T1
ΔT = 20°C - 25°C
ΔT = -5°C
50208 j = 2.50 g . c. -5°C
50208 j = -12.5 g.°C .c
50208 j /-12.5 g.°C = c
c = 4016.64 j/g.°C
