To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.
To calculate the energy required, you can use the formula: Q = mcΔT Where Q is the energy in joules, m is the mass in grams, c is the specific heat capacity, and ΔT is the change in temperature in Celsius. Given the temperature change is from 17°C to 34°C and you have the mass and specific heat capacity, you can calculate the energy required in kilojoules.
