Question

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!

Answer 1

1°C

Step-by-step explanation:

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

`Q=mc\Delta T`

m is mass

c is specific heat

`\Delta T` is the change in temperature

ATQ,

`m_1c\Delta T_1=m_2c\Delta T_2\\\\m_1\Delta T_1=m_2\Delta T_2\\\\(100)/(1000)=(\Delta T_2)/(10^(\circ))\\\\\Delta T_2=1^(\circ)C`

Hence, the required temperature is 1°C.
