YUP IT CAN DECREASE IF THE SURROUNDING IS COOLER THEN THE BODY AND WHEN U R TALKING ABOUT THE REMAIN CONSTANT IT ONLY OCCURS IF THE TEMPERATURE IS SAME ALL OVER THE SURROUNDING AND THE BODY........

wen heat is given to a body it can be converted into internal energy or as work...if the system does more work than the supplied heat then the internal energy decreases resulting in the decrease in temprature...if the heat is used in phase transition then the temperature of the body remains constant

yeh...... nooooo.... wait hypothetical q?. if we heat a body it's temperature increases. But after a time, it's temperature might again decrease. this is due to the passage of heat from body to it's surroundings. finally, body comes in thermal equillibrium with respect to surrounding. The temperature reached finally is more than the previous one. Note that, if the surrounding is too large either in mass or space, and relatively low temperature we can neglect the temperature increment, in the senbse it remains constant.
