Question

M=1,5 Q=920Дж t1=10C° t2-?

Answer 1

Дано:

m=1,5

Q=920 Дж

t1=10°C

t2=?

Решение:

Формула

t2-t1=Q/cm

t2=Q/cm+t1

t2=920/1,5+10

t2=80

Answer 2

It looks like you're trying to calculate the final temperature (t2) of a substance when given its initial temperature (t1), energy added (Q), and its heat capacity (M).

The formula to calculate the change in temperature (ΔT) of a substance when heat is added is given by:

Q = M * ΔT * c

Where: Q = Heat energy added (in joules) M = Mass of the substance (in grams, in this case, it's not provided, but you need it) ΔT = Change in temperature (in degrees Celsius) c = Specific heat capacity of the substance (in J/g°C)

Since you have Q, M, and t1, you can rearrange the formula to calculate ΔT:

ΔT = Q / (M * c)

However, you can't find the final temperature (t2) directly with the information given because you need the mass (M) and the specific heat capacity (c) of the substance. Once you have those values, you can calculate ΔT and then add it to the initial temperature (t1) to find t2.

Please provide the values of the mass (M) and the specific heat capacity (c) of the substance, and I can help you calculate t2.
