When temreture increases, the frequency of a tuning fork

To reduce the frequency of a tuning fork –

A tuning fork vibrates at a frequency of 256 Hz . (a) When the air temperature increases, the wavelength of the sound from the tuning fork : (i) increase, (ii) remains the same, (iii) decrease. Why ? (b) If the temperature rises from 0^@ to 20^@ C , what is the change in wavelength ?

Does the frequency of a vibrating tuning fork change on increasing the temperature?

How does the frequency of a tunning fork change, when the temperature is increased?

When prongs of a tuning fork are rubbed, its frequency decreases.

The prongs of the tuning fork are filled a little, the frequency of the tuning fork after filled
