Need help on physics lab please

Question

Foxboy · Answer

i can help

JST02 · Answer

Thanks. Here is the first page. I know that ytou use Q=mc delta T to find the predicted temperature, but I am unsure how to do it.

Foxboy · Answer

i'm not on that yet sorry

JST02 · Answer

Ah alright

@JST02 i am available

redhead23 · Answer

but i am not sure tho giv me a sec

jhonyy9 · Answer

- my idea ,so i think it in this way - you need to know that delta T = t_1 -t_2 the average change of temperature

jhonyy9 · Answer

so and about this please @imqwerty ? ty

imqwerty · Answer

1) find the temperature of both the water samples. The one with more temperature is hot and the one with less temp is cold.
2) start the timer and mix them

the heat will go from hot water to cold water until they both attain the same temperature.
heat lost by hot water = heat gained by cold water

$\large{m_{hot}c\Delta(T_f - T_{hot}) = m_{cold}c\Delta(T_f - T_{cold})}$
