Revolutionary War soldiers made their own musket balls by melting lead (Pb). How much energy
Sati [7]

Answer:

Q = 813.12 j

Explanation:

Given data:

Mass of lead = 21 g

Initial temperature = 25°C

Final temperature = 327.5°C

Amount of heat absorbed by lead = ?

Solution:

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

ΔT = T2 - T1

ΔT = 327.5°C - 25°C

ΔT = 302.5°C

Specific heat capacity of lead = 0.128 j/g.°C

Q = m.c. ΔT

Q = 21 g. 0.128 j/g.°C.302.5°C

Q = 813.12 j

Which feature do all adult echinoderms have?
Lana71 [14]
The phylum Echinodermata , which contains about 6000 species, gets its name from the Greek, literally meaning "spiny skin." Many echinoderms actually do have "spiny" skin, but others do not. This phylum exists exclusively in the sea, and cannot be found on land or in fresh water. All echinoderms have one thing in common: radial symmetry. This means that the creatures have appendages (or body construction) which point outward from the center of the body like the spokes on a bicycle wheel. Furthermore, these appendages usually occur in multiples of five, although there are a few exceptions. There are several well known members of this group, like sea stars and sea urchins. The radial symmetry is obvious in these creatures.
