Answer:
20 km
Explanation:
he walks 10 km + another 10 km so 20 :)
When heat energy is supplied to a material it can raise the temperature of mass of the material.
Specific heat is the amount of energy required by 1 g of material to raise the temperature by 1 °C.
equation is
H = mcΔt
H - heat energy
m - mass of material
c - specific heat of the material
Δt - change in temperature
substituting the values in the equation
120 J = 10 g x c x 5 °C
c = 2.4 Jg⁻¹°C⁻¹
Answer:
I don't know I'm sorry I will tell you another answer asks me to
Answer:
d
Explanation:
(d the water and metal will adjust to the same temperature between 10 degree c and 120 degree c this temperature will be call equilibrium temperature
