Answer:
Melting point is the temperature at which solid and liquid phases of a substance are in equilibrium.
Boiling point is the temperature at which its vapour pressure is equal to the external pressure.
<span>We can use the heat
equation,
Q = mcΔT </span>
<span>
Where Q is the amount of energy transferred (J), m is
the mass of the substance (kg), c is the specific heat (J g</span>⁻¹ °C⁻<span>¹) and ΔT is the temperature
difference (°C).</span>
According to the given data,
Q = 300 J
m = 267 g
<span>
c = ?
ΔT = 12 °C</span>
By applying the
formula,
<span>300 J = 267 g x c x
12 °C
c = 0.0936 J g</span>⁻¹ °C⁻<span>¹
Hence, specific heat of the given substance is </span>0.0936 J g⁻¹ °C⁻¹.
Because it goes from a somewhat solid state to a liquid state.

Answer:
Una partícula subatómica es aquella que es más pequeña que el átomo. Puede ser una partícula elemental o una compuesta, a su vez, por otras partículas, como los quarks que componen los protones y los neutrones. ... De esta manera, se han descubierto docenas de partículas subatómicas, y se teorizan cientos de otras más.
