The number of joules needed to raise the temperature of 100 grams of water by 10°C is the same as the number of joules needed to raise the temperature of 1,000 grams of water by what? Hint: Look at ratios – you don't need to do the q = m•Cp•Δt calculation!

Respuesta :

Answer:

1°C

Explanation:

We know that the heat required to raise the temperature is given by :

[tex]Q=mc\Delta T[/tex]

m is mass

c is specific heat

[tex]\Delta T[/tex] is the change in temperature

ATQ,

[tex]m_1c\Delta T_1=m_2c\Delta T_2\\\\m_1\Delta T_1=m_2\Delta T_2\\\\\dfrac{100}{1000}=\dfrac{\Delta T_2}{10^{\circ}}\\\\\Delta T_2=1^{\circ}C[/tex]

Hence, the required temperature is 1°C.
